Ubuntu :: Screen Flashes Several Times, Mouse/cursor Pointer Disappears
Oct 31, 2010
I'm running Ubuntu 10.10 which I recently installed on this emachines w3107. For some reason, while doing whatever I may be doing, my screen will flash off and on for about a minute, then when it stops flashing; there is no mouse pointer visible. I can still use the mouse, but it's ghost-like.
I'm running 12, not 11. I don't know why I had 11 in my head. Can this be moved BACK from EOL? If not, I'll start a new thread. Sorry. My wife and I have matching HP EliteBook 8730w "mobile workstations" (laptops that need a donkey to move them). We also have matching LG second screens. Unfortunately, we have matching mouse pointer issues too, as you might expect.
99% of the time we work away without issue. 1% of the time, Fedora suddenly stops showing the mouse pointer in the separate LG screen. The pointer is there, you can use it (if you can guess where the hell it is!) but you can't see it. Only a reboot seems to solve the problem.
It's worth noting xorg.conf is not being used. It's an nVidia card in these laptops and I tried the latest drivers from them - they totally wiped out the display, I mean total FAIL, unusable. Had to boot up in without GNOME, run level 3, to fix it. After much messing around, I think I used the FirstAidKit plugin for xserver to repair things. Since then there is no xorg.conf:
If I restore *any* xorg.conf file it all goes wrong again, so I'm guessing there are either some defaults at play or there's another system currently managing my display. Either way, restoring/editing xorg.conf won't help me with the current set-up.
When I close the lid on my laptop, it blanks the screen but does not sleep or hibernate. When I open the lid, the screen wakes and everything runs, but my mouse cursor has disappeared. I can restart the desktop ctrl-alt-backspace and get my mouse back.
My hardware: - Lenovo Thinkpad X61 Tablet - Intel GM965 video - Ubuntu Jaunty (v9.04)
Did a quick search for these symptoms and couldn't find anything related. After upgrading to 10.04 I found that the computer (HP NC8000) now crashes frequently and at random intervals. It occurs sometimes after only a few minutes, other times after an hour or two. It happens while its in use, or while its idle, wether the screensaver is on or not, even if its locked and the lid closed. When I walk away and come back I find the screen has gone blank (except for the Mouse Pointer and a cursor in the top left) and the Caps Lock Light and Num Lock Light are flashing (signifying a crash)
I caught it while I was using it and watched as the screen suddenly went blank as described above. No errors or explanations or warning. A reboot restores order, but not for long. Some assistance with diagnosing this would be helpful. I suspect it could be ATI radeon 9600 mobility related, as with each passing version of ubuntu it seems to be more unstable
I have installed Ubuntu 10.04 and when i log into the system my mouse pointer/cursor disappears and I have to leave the system idle for 5 minutes after that the system gets locked and when I unlock the system I get the mouse pointer/cursor back. How to resolve this I want to see the mouse pointer/cursor when I login to the system. Can anyone help me to fix this.
I'm relatively new to Ubuntu and I have a question. I have compiz config settings manager and I did some changes there but I've noticed now that for example when a skype chat window is open and when I move my mouse pointer away, the window disappears. It's not exactly like disappearing cause when I hover over the window, it shows itself but it's pretty annoying ;/ I've changed so many settings but no result
No matter what kernel I select to boot into, eventually I lose the mouse pointer visibility. If I move the mouse around, stuff does get highlighted, I just can't see the pointer as it moves. CTRL/ALT/BKSP does bring up a logout menu (doesn't kill X, tho), and I can tab thru it...time wasting, although it does come back from a restart with all the windows as before.
I'm running Gnome. Cpu is AMD Athelon 64 3800+ OS is 32 bit. I didn't normally have this problem before. Do I need to return to 11.0 ? Is this a Gnome problem or an X problem. I seem to remember that KDE4 had a utility that would grab the pointer from the ether and stick it back on the screen
I have had continued issues with my graphics: [URL]... Now, after an update manager update, I have a new issue. My mouse cursor disappears when I use my external monitor beyond a given resolution. Also, my settings for the laptop monitor are incorrect (will not let me select the true laptop native resolution). I even had an instance when I had mirrored images, but saw the mouse pointer only on the laptop screen, but not on the external monitor. I also recently did the suggestion to
Which had caused issues when I was previously running Ubuntu in dual boot with WIN XP. I am now on standalone Ubuntu 10.04. I reversed the grub edit, but the problem persists. Currently, I have to keep my external monitor at a much lower resolution for mouse pointer to show up, or use the CTRL key to show mouse pointer location feature in higher resolutions. All other aspects of the higher resolution for the external monitor work well...just that my mouse cursor does not show up.
I installed Suse 11.2 recently, and i have my laptop hooked up to a HD monitor. When i choose the HD monitor, if the resolution is low, lets say 1280x800, same as my laptop, its fine. I see the mouse pointer.
But as soon as i change the resolution to 1920x1080, the pointer disappears. Mouse functionality works allright. Right click/left click works fine, and i can see the buttons getting highlighted on mouse-ever. But the pointer is gone.
I just upgraded from 8.04 Ubuntu to 10.04. The mouse cursor works fine during login. As soon as the system switches to the desktop, the arrow cursor "image" disappears (remains working ..you just can't see it). The OS will also randomly shut down requiring a re boot. For the mouse cursor I am currently using a work around which is to hit the control button which "locates" the mouse and once located, I move to select and open gnome terminal. Typing a couple of Chars. and mouse movement brings up the "I" bar cursor image, and then the mouse image will operate properly until re boot, where the issue returns. On the random shut down I am not 100 percent that the system has shut down... it may be that the PC is turning off the monitor (the monitor appears to power cycle over and over until cntl-alt-del is pressed). As far as the PC I am using:
Dual Boot Linux on hda and XP Home on hdb.PC is Dell 2400 (I believe built in Intel 945 video card) Problem only occurs with Ubuntu 10.04 not reproducable under WinXP so I believe the problem to be kernel or driver issue in Ubuntu. I have checked several forums and bug reports but have seen no solutions although there seem to be several users with similar/same problems.
I use a laptop, and frequently plug in to a separate monitor or to a TV screen. I have it set up to to separate X screens. When using my laptop touchpad, I find that once I move to the other monitor or TV screen, I can't return back to my laptop monitor. My USB mouse, however, is able to transition from screen to screen with no problem. I am using ubuntu 10.04 but had the same problem with 8.04 before I upgraded. I have an NVIDIA graphics card, and use the nvidia-settings (which generates the xorg.conf file) to manage the screens. Here is my xorg.conf:
Code: # nvidia-settings: X configuration file generated by nvidia-settings # nvidia-settings: version 1.0 (buildd@crested) Sun Feb 1 20:25:37 UTC 2009 # nvidia-xconfig: X configuration file generated by nvidia-xconfig # nvidia-xconfig: version 1.0 (buildmeister@builder58) Fri Aug 14 18:33:37 PDT 2009
I am using Ubuntu 10.10 on my Dell Inspiron 1525. I haven't have been having consistent internet connection, hence haven't updated for much of the time. Yesterday I tried to update the Firefox browser from 3.6 to 4 and ran
sudo apt-get install firefox
It told a amount of around 57 packages would be updated in the process. After the installation I shutdown and went to sleep.The system now boots to purple screen ubuntu dot loading and then to black screen with the mouse pointer in the centre. Then nothing happens. I searched in the forums and tried to go to recovery mode and ran dkpg, then failsafeX, but failsafeX cannot detect my input devices, Hence I can't do anything.
I installed Ubuntu 11.04 today as the main OS on my laptop.I had deleted my XP partition, and repartitioned it according to a guide I had found. (http:url)......Basically it was setup like this: 500mb ext2 primary partition, has the grub folder, I believe this is either the '/' partition, or the '/boot' partition 2gb swap space logical partition
10gb ext4 logical partition -- this is either the '/' or the '/boot', it contains the 'bin,boot,cdrom,dev' etc folders 243gb (the rest of my hard drive, with the exception of a partition that contains documents and files from my XP OS, formatted to NTFS) ext4, this is the one that has all my desktop/documents/etc folders.After Ubuntu was done installing, I had some message pop up about installing an ATI proprietary driver for my ATI graphics card (an ATI Radeon HD 4330, I believe, I may have messed that number up). I installed it and rebooted, no problem.
Next, I had another update window pop up with 198 items checked and ready to download and install. I went through all of this, and rebooted, again, no problem.Next thing I did was install some apps that were essential for me to have to use for my work (an ide, chat programs, etc). No problem with any of that.Last thing to install was the OSE Virtualbox, and then I installed WindowsXP Pro and Windows Vista Business, then installed the guest addition addon for VB. This all worked without any issues whatsoever.
Time goes on, and I notice my computer is heating up much more than (seemingly) normal. I begin to wonder if its my graphics card. So I shut down the computer and let it cool down. Reboot, and no problem, still working fine.Then I opened a couple of apps and tried a simple game (can't remember the name) I believe it was a simple 3d topdown, as I wanted to test my graphics card. This is where things seemed to start to go wrong. My laptop began hanging, not even allowing me to access the terminal via ctrl+alt+f2. The screen flashed and I saw the blue/green/grey fuzz that I get when the graphics card is starting to heat up too much. Then everything hangs and I can't do anything at all, including move the mouse. I did a hard reboot (I believe this is what you call pulling the plug/pressing the power button, correct me if I'm wrong). I then rebooted, saw a chkdisk, then it booted seemingly normal, but it hung right after the purple screen after the grub screen.
This is pretty much where I'm at right now. I strongly suspect the fault is with the ATI drivers, but have been completely unsuccessful in my attempts to fix it. I've googled just about everything I could think of, along with searching these forums. I've tried just about everything listed in the forums, but to no avail.I've tried the commands that are supposed to purge the ati drivers, but all I get are errors that say they can't remove the 'virtual drivers'.
Right now I'm booting off a live cd, so I know the computer still works fine, just not my actual installed OS. I'd really like to get the issue resolved without having to reinstall, as it took quite awhile just to get it usable in the first place, but this has already taken so much time, I may just resort to that if we can't solve it any other way. Got too much work to catch up on as it is.As a re-instated note, perhaps if you have any tips, but not particularly about fixing the OS, my laptop (I'm strongly guessing my graphics card) is heating up much more than normal, compared to that when XP was installed. Is this more than likely just a driver issue, as is the rest of it? Also, I did have Compiz installed, though I didn't choose for it to be installed, I believe it came pre-installed. I've heard it could cause some issues, though I have no idea as to the validity or relation to this particular issue.
Edit: I just remembered while searching for a solution, I found a post somewhere that said something about the information not being sent to the monitor from the graphics card properly, thus no desktop. I'm guessing that'd still fall under the driver issues, but again, I'm unsure. I would think that wouldn't be entirely true anyway, since I can still see my mouse fine, just no desktop, only a black screen.
I've installed Ubuntu 10.04 on an old PC with an Intel 845 series motherboard, using an onboard graphics solution. By default, it boots with an 800x600 screen resolution. When I change the resolution to 1024x768, the resolution switches perfectly, but the mouse pointer disappears. The mouse can still be USED, but I have to 'guess' where the pointer is. The only way I have found to rectify the situation is to reboot, upon which the resolution returns to 800x600 again as well. Kubuntu 10.04 suffers from the same problem, only in Kubuntu the mouse pointer reappears when the resolution switches back to 800x600, so I don't need to reboot.
I've installed 11.2 KDE on a very old samsung V20 specs here: [URL]... My problem is that when I boot I get a black screen with just the mouse pointer. I can boot in failsafe fine, but the graphics are horrible. My question is, is there a workaround or am I flogging a dead horse with this laptop? This is my first venture into Linux, and I was really keen on leaving windows far behind. I've tried quite a few sax2 commands to no avail.
I have Open Suse 11.3. I normally use GNOME or KDE sessions. Yesterday I was just thought of trying other Desktop Environments. so I logged out to choose a different session. I tried LXDE and logged back out. After that I found "metacity" in the sessions list and tried it. But no desktop appeared. All I got is black screen a with the mouse pointer/cursor. I waited for quite some time but no desktop, panel, etc loaded or was visible.
I could not figure out how to log off so I hit the start button. After reboot the system automatically chose the same session (It always reuses the last used session) and I was in the same sticky situation. I tried starting in Safe mode as well but still I get the same black screen with just the mouse pointer.
have a problem with an Acer Aspire one running linpus linux. I get a black screen with a white mouse pointer at startup. I don't know how this happened. I can interrupt the startup process with ^c and then see the following amongst other text :Loading x11 FronEnd module...Failed to laod x11 FrontEnd moduleFailed to launch SCIM
I just recently installed Slackware onto a virtual machine(I'm planning on buying a new disc drive and 1 TB HDD with-in the next couple of months and plan on Slackware being my primary OS[right now Mac OS X 10.6 is]), and everything went great.
I then went onto edit the /etc/inittab file in emacs and changed the run-level to 4. I don't know why it's decided that I'd want to boot into KDE when XFCE is installed and in the configuration I selected XFCE but it's not really relevant(I have a WM guide thing open in another tab and will probably be able to change it).
The problem is, as the vague title may suggest, is that it basically freezes when I'm at the log-in screen. The input field for the username is highlighted and blinking, and the cursor it self is visible in the centre of the screen, but it simply doesn't pick up on any input from my keyboard or mouse.
I tried booting up the install CD and logging in as root, mounting sda4(which is the root partition) and editing said file but sudo isn't installed(to my knowledge) on the install disc and when I do the command,
I had a perfectly well running CentOS 5 system but with an old crappy monitor. I replaced the monitor by a bigger one, i did a monitor detect to make sure that CentOS would recognize the highest possible resolution. Then changed the display rsolution for the current user.
Now when i login as root just a black screen appears with a white mouse pointer and then nothing. I already deleted all the contents in the home directory /root but no improvement.
When i login as a new user X is starting perfectly.
Anyone have a clue what i need to do or delete to get X working again? I can nuke the whole box and do a reinstall but i'd rather not.
I have been trying hard to configure wizardpen for my ubuntu laptop.wed abletSetupWizardpen link for the info. Still it doesn't work. When I put stylus pen on the tablet, mouse pointer goes to the top left corner of the screen and stay there. Not sure what is going wrong.
I'm a linux newbie so go easy on me with technical terms.I've got a Acer Aspire One ZG5. Everything was working fine until one day when I went to switch it on and it shows up everything its suppose to, the blue logo etc but then it loads upto a black screen with the mouse poitner. I can move the mouse pointer around and such and the lights flash but stop suddenly.I can't use the bios recovery disk as I haven't got a USB big enough.
I currently have my computer connected to my main monitor, as well as my TV. I am using the Nvidia Driver and they are running as separate X screens. I have currently run into the problem that if my wife is watching videos on the TV while I am surfing the web or something on the other monitor, we really need 2 seperate cursors.Is there some way to have each X screen own a seperate cursor controlled exclusively by its own mouse? Or is there some other solution to this that anyone can think of?
I've been trying out suspend occasionally on Debian Testing to see if it works. After the last time though Gnome won't come back up again, I just get a movable mouse cursor and no panels or right-click options even after rebooting. I can switch to text consoles and kill X but starting it again results in the same behaviour. I noticed there have been a few Gnome and Xorg updates lately.
I have a machine running XFCE in a "kiosk" environment. The machine normally runs without a keyboard or mouse, and I remote control it via VNC and SSH.
When the machine starts up, the mouse cursor sits in the center of the screen. I don't want to plug in a mouse or use VNC to move the mouse to the bottom-right corner so that it is not visible, so is there a way to hide the mouse cursor or tell it to move to the lower right when X starts? It would be even cooler if the mouse could be disabled or hidden when no mouse is connected, but re-enabled when someone plugs in a mouse, but that's probably asking too much.
I have two monitors set up on my Asus N61J laptop, but have a weird problem:When I move the mouse to right-hand edge of the Left (Primary) screen, it disappears. To get it back, I have to either keep moving it to the next screen, or move it over something that will cause it to change shape.It also happens if I move it to the left-hand edge the Right (Secondary) screen. Anyone have any ideas as to how I can fix this? It's a little annoying, as it makes it hard to select the Logout/Shutdown/Status menu
In KDE I'm using KWin as windows manager and somewhere in the configuration I defined that KDE should rotate the desktop cube to the left or the right each time I move my mouse pointer to the far left or right of the screen.If I keep it there for about a second it rotates the desktop cube to the next desktop.I once activated this but find this very frustrating when I'm trying to reach buttons on the same side. So I want to disable this feature but I can't find it anywhere. I can't remember where that option was that activated this feature.
I run a HTPC which I recently upgraded 11.2 -> 11.3.Most things work fine but I've got an oddity. After the TV is shut down and restored the mouse cursor is "frozen":The old mouse image stays where it isHowever, the mouse IS active, in that you can (blindly) move the mouse, see it mouse-over widgets, and activate them - there's just no visible cursor where the hotspot is.Hardware is ATI chipset (can't remember which, offhand, but it's only a year or two old), running AMD driver, with a HDMI link to the TV.
Redhat Ent Linux ES Release 2 (Taroon 8) Kernel 2.4.21-4.ELsmp startx(1): initialize X session - Linux man page
I thought I'd look into methods of recovering from a lost password for future use, how to change the passwd and shadow should I need to. So I started an X session, vi'd my .swp files then logged off. Perhaps I changed one of these files accidentally, but my intent was just to view them which I did. After starting up my computer the next day and logging in I began an X session - "startx". The session appears to have started, but with a black screen and an active mouse cursor.
I am using a wireless Xbox 360 controller with openSUSE 11.1. I use it for some emulators and all buttons work fine. There is however an annoying problem, the Xbox controller left joystick controls the cursor and digital pad acts as mouse buttons. So while I play, the cursor moves all around the screen and bad things could happen. Why this behavior? In xorg.conf there seems to be only just 1 mouse. And if I go in Joystick via YaST, there is only a menu to select which joystick I have. But my wireless controller has been automatically detected, I didn't setup anything. Is there a config file that I can modify to stop controlling the mouse with my gamepad?
