I'm getting the occasional full-screen black flicker on my laptop, it's an Asus G73JW with an nVidia 460M card, running the restricted drivers. I've installed Gnome3, and so far like it more than Unity, but the flickering needs to stop
I've also noticed that some animations aren't as smooth as they should be, like when I hit the top-left corner to bring up the dock it studders just a wee bit.
I have downloaded the ver10.04. I am running it on my laptop with a NVIDIA GeForce GO 7600 128MB graphics card. I am using the NVIDIA driver on the system. The screen flickers randomly after say every 1 min. By flickering I mean it just refreshes and goes blank for say 1ms during the refresh. It happens even more if I turn on CompViz option.

Everything works fine until I enable SLI with the --sli=AFR or --sli=OnOnce SLI is enabled there is extreme flickering relating to anything graphical.Including Compiz effects and any opengl software.Disabling SLI returns the compy back to it's good self.I would love to utilize SLI, however can't seem to find a solution for this bug.

I'm using a dual boot with Vista basic/lucid lynx on an Acer Aspire 5100 laptop.
I am having a funky issue at login. When I enter my username/password at login with the GUI (I disabled the list of users some time ago) the screen will flicker then return me to the login screen. There is no notification of an error. It doesn't matter if I try the recovery console or safe mode there is the same issue when I try and login with this user. However, I can login with a different user open a console and su to that user that wouldn't login at the GUI.

All is well except for the following: after i power up my notebook, login and i can see the panel i plug the power cord in. And the my screen starts flickering in orangeblack colors. Nothing i do seems to take it out of this state but a good old hard-reboot.
View 5 Replies View RelatedI was on earlier 9.x version of ubuntu with following configuration working perfectly: IBM ThinkPad T60 with ATI Technologies Inc Radeon Mobility X1400 VGA graphics card (found it from lspci) With an external Dell 19" monitor attached to it. I upgraded yesterday to Ubuntu 10.4 LTS and now the Dell monitor screen keeps flickering all the time! I always work with an external bigger monitor attached to my laptop as working for long hours on the smaller screen of the laptop gives me headache. The frustrating point is, this setting was working perfectly until I was on Ubuntu 9.x, I upgraded to 10.04 LTS and this has stopped working.

After installing Ubuntu (Version 10.10 DVD �amd 64Ubuntu 10.10 live DVD).
On the following hardware
Gigabyte GA-K8VT800-RH motherboard

AMD Sempron 3400 cpu.

The screen resolution looked very good with all screen resolutions working well The colours and fonts very clear. All other device drivers worked 100%. But unfortunately the display flashes about every 10 seconds and the partial beak up of the display only lasts a fraction of a second and very distracting and is unusable. Testing with Ubuntu 10.10 live DVD. With this months Linux Format Magazine also exhibits this problem. However deleting the partition and installing Ubuntu 10.04 Beta1 DVD -386. And all updates downloaded. Works 100% with no screen flicker.
My G73JW works really great except for 1 thing. A change in the performance level causes short black flickering on the display, which is absolutely inacceptable (e.g. with compiz). Setting the preferred mode to "performance" locks the performance level and helps but seems like a bad solution (batter life and heat).
View 4 Replies View RelatedI was messing around with the screen orientation and thought it would be funny to orient it sideways. Big mistake The screen went black.I can force a shutdown, login and I get the same black screen. I tried hooking up an external monitor and the monitor showed no input so I'm guessing my laptop doesn't have that capability with Fedora.This is my main computer.
View 14 Replies View RelatedI am trying to solve multiple issues with my 64x natty install using gnome3 ppa( official ppa from gnome3). I have this setup on two machines, one is a fresh install the other is a upgrade. They both have most of these issues. Here they are: 1) Nautilus will not launch from the favorites bar. It does launch from a shortcut on the desktop. It will not run from the terminal unless I am root. 2) Number lock is disabled at startup (enabled in my bios). I used to be able to enable after nattty had started, I no longer can, though num lock light is lit - number keypad does not work!
3) I have set gnome3 set to let nautilus draw the background and desktop, I get a white screen at boot until Nautilus is launched then I get a background and some desktop icons(no computer or network icons). If I plug in a usb drive the icon appears on my desktop, when I select it I loose the background and have to select it again.
4) Wireless randomly will drop the connection, have to reconnect, sometimes it will, sometimes I have to reboot. I have Fedora installed on a 2nd hard drive on the machine with a clean install and the only similarity is it displays the default desktop until I launch Nautilus, then my background and desktop are displayed with all of the icons. From there on out Fedora has none of these issues. I have used Ubuntu Gnome and XFCE as my only os since 6.0 and have never had this many problems. Both machines would not run the gdm because of Nvidia issues after the upgrade and clean install. I DO NOT want to give up on Ubuntu as I tell all my friends and family to use it.
I can't seem to get Ubuntu to run on my old Dell Dimension 2300. It boots to a purple screen then it goes to a black screen with a load of writing nothing else happens after this screen. [URL] Could someone advise how I can get it to work?

I think... the user "Jetty" may be a part of (or has something to do with SQL?).. This machine I have is not a server (in fact I know pretty much nothing about web servers).. this machine is used purely for local app development (python PyQt4/ and C++/wx - making games, general utilities, specialized calculators...etc)
So... Can anyone please tell me who the user "Jetty" is ? (The others are safe, I compiled python/SIP/PyQt4/wx/aliens from source... so that;s probably why it doesn't belong to packages.
Plus, My screen started to flicker some time (could it be possible someone is messing w/ my xorg configs?)
I've just installed Ubuntu 10.4 alongside Windows. During the installation process, everything was black, then it flickered for a couple of seconds, then went black again. This happened many times. After the installation, I was hoping it would stop, but the same thing happens at the login screen. It flickers for a couple of seconds, then goes black. I figure it has something to do with my display drivers, but I don't know how to install them without using Ubuntu. If it makes any difference, I have an ATI Radeon 4890 video card.

View 1 Replies View RelatedI have recently installed 11.04 natty on Intel Core i3-2100 3.1 GHZ using its own graphic accelerator. When the screen is idle for a long time, more than 1 hour, I get a black screen with the mouse arrow but nothing else. the mouse moves the cursor and Ctl+Alt+F1 does work. How to fix this problem?
View 4 Replies View RelatedI 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 have Ubuntu 10.04 running kernel .26 installed on my Dell Dimension 2350 with 512mb of memory. The problem I have been having is, When I am using the computer mostly Internet stuff for no reason the monitor will go black then on the screen it will be at a terminal screen, kind of like when you start up the computer, I don't remember what is all on it but the last thing in the list was: checking battery state: OK after that the screen will flash in multiple colors and then it goes into a loop of just black screen than a colorful flash and back over to a black screen. the only way I can fix that is by holding down the power button. this will happen mostly on face-book on the games and just on the profile page, but it does happen just checking my gmail or play solitaire it does this around 4-8 times a day.

I'm trying to test out using xubuntu 10.04 on my one computer and keep getting a black/blank screen after selecting the 'try' menu option.Is there a way to fix this?I have tried some of settings via F6 with no luck.
FYI -The CD works fine as I have tested it on other machines.The version I am trying is xubuntu x86 (although I have tried ubuntu 10.04 x86 with similar results).I can Alt+Ctrl+F1 fine and get to the cmd prompt
This obnoxious bar has just appeared in Smplayer at the top of the screen. It stays there even when I go full screen. Now full screen isn't full screen and there are black edges on both sides of the screen. I have not be able to figure out how to hide it. I do not need or want this onscreen display. How can I configure Smplayer to make this go away? How can I get my 16:9 full screen aspect ratio back? I have done nothing to mplayer or smplayer as far as editing any or changing any configuration files. I tried several videos and it displays on all of them. It was not there last time I used Smplayer.
View 9 Replies View RelatedI have openSUSE 11.3 with an nvidia card connected with two monitors. In the past I used xinerama which was ok, but now I need to have two separate desktops, one on each screen. I set the nvidia driver with x screen, and now one screen works perfect and the other only shows a black screen. When I move the mouse over the black screen, the mouse pointer turns into an X, but moves correctly, which seems to me that the problem is that I need to set the second desktop to that screen. I looked on forums on how to do so, and no luck.
