I installed the latest KDE desktop on my Ubuntu 10.04 system. When I switched to KDE the screen ends up black with no access to anything. I reboot but don't have access to the session manager on the ubuntu login screen so I can't get back into my Ubuntu desktop. What can I do?Embarrasingly, I had to log on via Windows 7 (its a dual boot setup) to gain access to the Ubuntu Forums
View 5 RepliesI have installed Fedora 8 before 5 months. I normally use Eclipse, java, firefox, tomcat. Nowadays when I am working in any of the said applications suddenly my desktop goes off like a blank screen as if my monitor switched off. After 30 secs or sometime the user login page comes. I need to restart all my work again. I use gnome.

View 1 Replies View RelatedI've upgraded from Karmic 64-bit kubuntu to the RC build for Lucid. I have two pcs connected to two monitors via an Aten dual head KVM switch. With the new release I only get a background slideshow on one monitor. I can get an image on the first monitor by right clicking and choosing Next Wallpaper image, but it never changes. When I select Desktop Activity Settings both monitors go entirely blank, except for the mouse cursor. The Display Multiple Monitors screen has ticks in all the multiple monitor checkboxes and Identify All Displays correctly identifies both monitors.
View 1 Replies View RelatedAn ubuntu-11.04 laptop is set to turn on the screensaver after 5 minutes of inactivity, and power management is set to blank the display after 15 minutes of inactivity. When the screen goes blank, you're supposed to be able to move the mouse to return to your Gnome desktop. This works sometimes, sometimes not. When it doesn't, moving the mouse doesn't eliminate the black screen, although I can see the mouse cursor. ctrl+alt+del does nothing, neither do alt+tab, alt+esc or ctrl+alt+esc. ctrl+alt+f1-12 work as they usually do, so I can "sudo /etc/init.d/gdm restart" from one of the TTYs, or via ssh.
I tested just now with setting the screensaver and power management display blanking to 1 minutes. After a minute the screen went blank (backlight on), and then after a second or two black (backlight off), and moving the mouse returned to Gnome as it should. So I don't know why sometimes it doesn't. Two questions:
1- Which program can I run, or which service can I restart, to return to Gnome without having to kill gdm and lose all open windows?
2- What's causing this?
I am having the same problem, as soon as X tries to load my screen just goes blank. I have an ATI Radeon 9550. At first I tried switching between VGA and DVI as well but upon ruling that out, I switch to my on-board video card and that is working thus far, but I'm trying very hard to figure out a way to be able to switch back. Anyways I'll check back in later on if I have any new information I will post.

View 2 Replies View RelatedI just put on my Linux PC now and after booting logging into the user a/c, it just gives a blank screen with the desktop wallpaper - no menu's or anything, so there's pretty much nothing I can do. I know I had removed the menu and replaced it with the dock (awn dock or something).
However, I can log in as root and root works fine (so I'm doing the update at the moment).
Coming back to my question, I used to know an Ubuntu command which I put in as sudo (terminal)and it used to work like a magic command which would literally restore and repair my linux installation - I even used it when I bought a new system and transferred my linux hard drive from my previous machine to the new one and this one command actually setup and prepared my linux installation to work smoothly in my new PC - just one command after connecting my h/drive in the new PC.
Lucid is not in testing but it's released.It seems it works now, with all desktop effects activated and switching users and closing sessions.The only thing I still don't know is which screensaver can I use if removing gnome-screensaver?

Is there a known problem with the Lubuntu 10.10 image here? I have downloaded it to two different computers, then burned the images to two different blank CD's (different brands) and neither loads. Both only get as far as the Lubuntu menu, once ENTER is pressed at that point to load the LiveCD, a blank screen eventually appears with a flashing cursor at the upper left of the screen, that's it. They were both burned using the slowest burn speeds available.
View 9 Replies View RelatedThe day started as usual until I got the very bright idea to install Ubuntu. A new OS along side W7, that sounded great. I checked some guides on the Internet, it was all very straight forward. Install it and Grub will show you the OS:es when you boot up. I installed Ubuntu, rebooted. After the BIOS messages the screen goes blank and my screen on-button begins to blink, as if trying to find a signal, I press enter, it reboots instantly. After BIOS messages I get to a screen that says "GRUB error: uknown filesystem grub rescue>"
I've looked through everything here and nothing works. I've tried to fix the mbr-thingy using Windows Repair and even though it says "one partition was updated with new boot-thingy" when I reboot, I get into that very same grub rescue. I think my setup has something to do with it. I run RAID0 (2x360Gb hard drives), first having C: at 50Gb and then the rest as F: for programs and such. What I did was that I shrunk the F: part and then used that as partition for Ubuntu. Also please have a look at these screenshots, my partitiontables and such seems completely wacky to the raid: Where should the boot-loader go? I'm very, very new at this. I've had Ubuntu Netbook remix on my netbook for a time but still treat me as an utter beginner.
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
I fixed this issue on 10.04, but just recently (1 hour ago) upgraded to 10.10 and am having the same issue. Machine boots fine, but the screen is blank for most of the boot, and plymouth is up for about a half second before I get to the login screen.I've tried searching the threads, but for the life of me I can't find the solution and can't remember what I did to fix it on Lucid.
View 4 Replies View Relatedlike any other Linux newb, I came to Ubuntu because my Windows crashed one time too many. And I chose Ubuntu because "it just works". But these past few days that hasn't been true. I'm posting this from a netbook with Ubuntu, and am having no problems whatsoever, but normally I use an Acer Aspire 5920G laptop. I'll include the specs as written on the sticker:
* Intel Core 2 Duo processor T5250 (1.5GHz etc)
* Up to 1024 MB Nvidia Geforce 8600M GS Turbocache
* 2 GB DDR2
Let me know if you need more details, and I'll add them later. Now, what happened was I clicked "hibernate" while leaving Firefox open. (I've done this hundreds of times, no problem) And when I went to turn it back on the next day there were weird graphical glitches in the loading screen, and it booted to the "tty1" prompt screen. I did a lot of googling and found quite a few posts about it, but the solutions either didn't work, or I didn't understand them. After trying several different suggestions from this forum and others, I managed to delete the graphics drivers. That enabled me to boot in low graphics mode, and naturally, I tried a whole bunch of things to make it work properly again. That only made it worse. Now it went straight from the loading screen to just blanking out and turning the display off. So, I tried new things. Over and over. The weird thing is even when I disconnected my harddrive and ran from a Live USB, the problem persisted. Could there be an issue with the graphics card itself? Anyway, after reconnecting the harddrive I tried to boot again. And it suddenly worked. Even HDMI to my bigger screen worked.

I have been running 10.04 quite successfully, when I upgraded to 10.10, I have a problem with the newer kernels. If I let it boot into the latest one 2.6.35-23, I get the Ubuntu 10.10 splash screen for a second then a blank screen, same with 2.6.35-22. I have to run with 32-25 to get it to load the gui.
I have an AMD Sempron 2800, 1.6GHz pc, but I'm not sure if it's running 64bit.
I've been running Ubuntu 10.10 very smoothly for a while now. Decided to upgrade to 11.04 - managed to corrupt the hard disk the first time by letting the laptop hibernate part of the way through but reinstalled from a live CD of 11.04 and it's now working except for this issue.
If I shut the screen on my laptop (or press the screen off button) either the screen won't come back on or it will but frozen (I can move the mouse but not click on anything etc.) In this state music continues to play (from spotify under wine) and if I press my hibernate shortcut (power button) the computer hibernates, only to wake into the same situation. I've got a Dell Latitude D520, upgraded to a bigger hard disk and more ram - the ubuntu partition has 50gb. Windows is working fine.
Edit: I noticed a sticky thread which includes something about a blank screen but I think this is a different issue?
i have just put a Geforce 7300 GT graphic card into my machine the problem is the max resolution I can get is 1024x768 at 60 hz the screen is a benq fp71g+. also the screen goes blank when i click on the display icon in system settings. i know that the screen can be run at 1280x1024 so I don?t know where the problem is.

I just recently installed 10.04 and the desktop look is nice, but all my applications, folders, games, firefox, etc... is missing. The only way for me to access anything basic is to browse through the fony folder I created just to try and find everything. getting at least my Firefox browser and some other basic applications. Oh and I noticed I don't have root access anymore either. I am the only one using the computer, but can't do a thing. I am running Ubuntu 10.04 on my Acer Aspire One Netbook. So I have no HDD.

At login screen, the bottom bar is present, but after I log in it disappears and all I'm left with is just the mouse cursor and the desktop background. This happens for both the Ubuntu and Ubuntu Classic choices. But both top and bottom bars are present when I choose the Ubuntu Classic (No Effects) and Ubuntu (Safe Mode) options. Is there a reason that this keeps happening? A bad install? Hardware can't support the new version of Ubuntu?

The PC boots up normally into Gnome desktop environment. When I hit ctl-alt-[F1-F6], -The screens blank out. One screen gets no video signal, as evidenced by a blinking power light The other screen is completely blank (not even a blinking cursor) If I hit ctl-alt-F7, I get the Gnome desktop back. I have been able to determine that even if the screen is blank, and appears completely dead, the system processes my keystrokes. For example, if I pretend that I am at the log-in screen and type <username> <enter>, then <password><enter>, then 'xinit -fg white -bg blue -- :1 vt8'<enter>, the PC switches to virtual terminal 8, and shows a shell window. From that point onwards, my keyboard entries show up in white-on-blue characters, and the behavior of this shell window is perfectly normal. I can log into another Linux box using ssh, start a Gnome / KDE / XFCE4 / LXDE session and work on the machine normally; or start another X-session and a desktop environment of my choice. My guess is, the console is invoked perfectly well; it is set to display black-on-black characters.
What I Am Looking For:Confirm if my guess about black-on-black console is valid.
Suggest how I could get a screen showing white characters on black (or indeed, any combination I could read)
I can boot Natty in classic mode only. When I try to boot to the Unity desktop all I get is a screen with nothing on it. When I installed it was booting to Unity fine. When I booted to classic mode then back to Unity I get the problem

As I am not familiar with Linux command lines I can't do very much. I have even tried reinstalling Ubuntu which showed no error messages that I noticed but, I have the same result. At the moment I have used Supergrub to allow me to boot straight to Vista till I get things sorted out.

even get access to the console for further debugging?
Anyway one day I start my computer and instead of starting normally it comes up with a screen which says GNU GRUB version 1.97~beta at the top. I selected the option Ubuntu, Linux 2.6.31-19-generic as I figured this is what normally loads without being prompted in the grub menu, but after this I got the ubuntu logo for a few seconds then my screen goes blank.

View 9 Replies View RelatedI'm a newbie so apologies if there is a trivial answer to this.
I (maybe somewhat rashly) tried to connect my tv to my laptop (Dell Latitude D400) running Ubuntu 9.10.
I plugged in the cable, went to the System>Display menu, where it had detected the model and make of tv (Samsung 19" LCD) (I think the resolution was 1650 x 1050 or similar). I clicked the box to activate the second monitor with the "Virtual resolution" adjusted. It told me to log out then log back in.
I accordingly logged out but then couldn't log back in. It had evidently changed the resolution not only on the 2nd monitor but also on the laptop monitor. A box was visible on screen but completely illegible/unclear since the laptop monitor couldn't display that resolution.
After a few restarts and button pushes it is now restarting at a terminal (I enter my username/password at a command prompt on an otherwise blank screen rather than the graphical interface loading up).
Question: are there any commands that could change the resolution back to its original settings then restart the Ubuntu graphic interface? Some thing similar to the "load with last known good configuration settings" option in Windows maybe.
