I have an old machine running Ubuntu 9.10 and XP.t is a P4 and Nvidia FX5200 card.Yesterday all of a sudden the screen started flashing black, the same type as when you install new graphics drivers and the resolution is changing. Only here it keeps happening over and over, the mouse isn't usable fully, the icons and menus are distorted, and I basically can't do anything.
I ended up reinstalling 9.10 and everything was working fine until I installed EnvyNG to get my nVidia drivers. It required a restart, and once I logged in the same thing started happening. So I said screw this, and installed 8.04. Yet even in 8.04, once I used EnvyNG to install the drivers, the same thing happened.A few other detailsP works fine, although one time a similar thing happened on XP (not as bad), and was fixed with a reboot.- This PC runs through a KVM switch, but I connected it directly and the same thing happens.I've found no help via Google. Sounds like a possible hardware problem, but it seems to work fine in XP and only acts up in Ubuntu once I install drivers.

I want to use my QTCurve theme for GTK apps. This has worked great for several months on opensuse 11.2, and suddenly it broke. I do not know what made it broke, purhaps some kind of system update...The gtk-Qtcurve engines are installed (both 32 and 64 bit). I tried linking the gtkrc file from /usr/share/themes/QtCurve/gtk-2.0 towards /etc/gtk-2.0 but that didn't help either. I can change the GTK themes to whatever theme, except to QTCurve...

I have a busted laptop, case that is. The internals are great. So I stripped the screen and built a large box. I used a cnc router to build a lid that would flush mount the screen, and have a lip of wood left to cover the metal edges of the screen.
Ok, what happened is that the measure twice cut once rule or one of its variants went into effect, and I put the hinge on the wrong side of the box. Normally I would say just flip the screen around, but one edge is wider than the other, so that will not do. I want have the hinge towards the couch so that I can tilt it up and be able to easily see the screen.
So I need a way to invert the screen, and I can't seem to find a way to do it. The coffee table is an Emachines N-10, and my video driver is the Nvidea one, because karmic told me my onboard card is not quite up to the task of the other one.

I have tried to connect my GMA500 based Acer 751 to an external dsiplay via VGA connection. I couldn't get the right resolution on the external screen (1920/1080) so I disconnected it and rebooted. Now there is only an "unknown" screen in the display menu. I have rewritten the xorg conf file per instructions for enabling GMA500 but to no avail - conf file looks right but screen is "unknown", low resolution and 4:3 aspect ratio, instead of 16:9. How to restore to laptop monitor - I think I can take from there to enable the right resolution.

Recently I install ubuntu 10.10 on my Sony Vaio laptop. After the CD boot I always got a black screen, after a week i figured that there's nothing wrong, it's just the screen doesnt show up on my laptop's screen. So I use an external monitor and It showed up as normal.
But I need to have it show up on my laptop's screen. I tried to use "additional driver" to activate latest Nvidia driver but after that even my external monitor doesnt work too. Latest driver doesnt work properly i guess. I did try to install older driver version manually but after I turned of gdm, install driver and reboot, my ubuntu always starts with tty1 command terminal. tried ctrl+alt+7 but it stucked at (checking battery state), startx doesnt help me return to graphical screen too.
I got help from a moderator here but the best result so far is to edit my /etc/default/grub. Change
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
to
GRUB_CMDLINE_LINUX_DEFAULT="nomodeset"
Sudo update-grub
after the reboot I have it shows up on my laptop's screen. But it seems low-bit color,a bit grand to me(compared to external monitor, both w/o driver). Anw i checked system/preference>monitor . It showed up that my monitor:unknown. I can't choose other resolutions, refresh rate = 0.
I always know its my widescreen is the problem. I have had a lot of problems dealing wgames/application (on windows) can't work on 16:9 mode. install a stable Nvidia driver
Everything I tried in the past weeks is in here [URL] My laptop is SONY VAIO VPCCW19FX, Nvidia GeForce GT 230M, widescreen monitor

Based on much internet searching, I've found that I was/am not the only one struggling to get Fedora 10 to span the display across a laptop screen and an external monitor. So what I have here are instructions to do so:
1) Fedora 10 does not (by default) use an xorg.conf file to configure the display. So type the following command into the command line: yum install system-config-display
2) Go to the menu bar and navigate to System>Administration>Display. I left all the display settings as they were and hit OK (repeat this step twice to make an xorg.conf backup). This will generate the xorg.conf and back up files in the directory: /etc/X11/
3) Now we need to see what size virtual screen you need. Type the following command into the command line (without the quotes): "xrandr --output VGA --auto --right-of LVDS" It will tell you that you are asking for a certain size screen. Write those numbers down. I have a 1600x1200 external monitor so my number is 2624x1200 (1600+1024 x 1200).
4) Change directories to /etc/X11 and type (without the quotes): "sudo gedit xorg.conf" Scroll down to where the device section is. Mine looks like this:
Section "Device"
Identifier "Videocard0"
Driver "intel"
EndSection
Some videocards need to turn 3d acceleration off in order for dual screens to work. It is important that you turn off desktop effects if you turn off 3d acceleration!!! So under the driver line add the line (with quotes): Option "NoAccel" "true" Mine looks like this:
[Code]....
Scroll down to where the screen section is, and then find the display subsection. It should look something like this:
[Code]....

I just installed Fedora 10 on my laptop (HP dv2500 series). I have it dual booting between Fedora and Vista. The laptop has one of those wireless on/off switches and next it the LED: blue - wireless active, amber - wireless inactive. It works fine in Vista but whenever I'm using Fedora it flashes between blue and amber quite fast, stopping on blue for maybe 4 seconds, then flashes again. I am on a constant connection to the network though, no sign of connection loss.

While using Ubuntu I have had few problems and it has generally just worked. One problem I have had is that while using my computer on occasion everything will be stopped and there will a message against a black background telling me the graphics card and screen could not be detected I have several options which are something like.
Run Ubuntu in low graphics mode for one session (which brings me to a normal login)
Run Ubuntu from a console (or something like that, it goes to a console)
Troubleshoot the error (I'm new to Ubuntu and never tried it)
Restart X (I never used it)
I think I missed one or two. "Run Ubuntu in low graphics mode for one session" works for me, but it is still a nuisance that I have to login again. It doesn't happen that often, not everyday at least and happens at random. I could have been using it for over an hour so I wonder why it suddenly can't detect the graphics card or monitor.

was trying to get rid of the ubuntu menu and try to change how the desktop looks. It's hard to explain but it was first the desktop you get when you first start up ubuntu on NetbookThen I somehow turned in into a desktop esque menu. With all the icons and stuff. Today my battery accidentally fell out as I moved it around and when I restarted my computer all went fine until the screen started flashing. On the upper right hand corner, was a transparent square with 2 arrows when it flashes. It still showed that I connected to my wireless and etc.

I tried to enable Compiz on my netbook, so I installed ccsm. Then when I enabled visual effects and restarted, my netbooks monitor starts flashing when I boot up. So I restarted in low graphics mode, uninstalled ccsm, and it's still flashing. Is there anything else I need to remove to get my netbooks monitor back to normal?b

Recently, whenever I restart my computer, I am automatically logged in and a rapid sequence of flashes repeats itself over and over. First a white screeen appears. Then my desktop background appears, dimmed and overlaid with the netbook-launcher's up and down arrows in the upper lefthand corner. Then my desktop background appears in full color, with my panel above it but no launcher. Rinse wash repeat. I assume it has something to do with Compiz. When escape to a tty and type "compiz --display :0--replace &" the loop ends and everything works. Any ideas how to avoid having to do this every time I restart

I've just downloaded and installed Ubuntu 11.04 (amd64) and every time I boot i get a flashing screen. I didn't have any problems at all with the LiveCD. The graphics card and my wireless adapter worked out of the box. But after the install it won't work. I can choose the OS in GRUB and then there's a purple screen. After that the screen starts flashing and I can hear the login sound.
I have tried using "nomodeset" but that didn't work either. There is no flashing, just a purple screen all the time. But it was possible to enter tty. I also tried booting the Recovery Mode but it just loads and then a pink flashing screen appears.
The graphics card is a XFX Radeon HD6870 1GB.

Offlate I installed F11 i586 on my laptop. F11 shares the hard disk with Vista Home Premium 32-bit. The problem is that when running F11 (or even Ubuntu), my system shut off suddenly(not a normal OS shut down, but a sudden power off without any warning). This could have been a hardware trouble(heating) but it doesn't happen with Vista.
Machine specifications:
Maker: Toshiba
Model: Satellite L305D-S5881
AMD Turion X2 Dual Core Mobile Processor RM-70
3072 MB 800 MHz SDRAM
I don't want to open up my machine unnecessarily, if it isn't a hardware issue.
I am not sure how to verify the bit length of the machine and the OS and does it create a compatibility issue ?
Your advise would be highly appreciated.

Once I installed it I've been having a problem where the screen flashes black for a split second. i looked up the problem and found this:I navigated to the directory it said, but I don't have an "options" file. What should I do? Are there any other fixes for this? It's quite an irritating problem.

I just recently installed Ubuntu 10.04. Every time I boot it up the screen flashes, like going off, then on again. It won't stop doing that. I can see the screen for 1 sec then it goes black, and keeps repeating this.

I recently wiped and partitioned my hard drive on my Sony Vaio Z series laptop. I set up the NTFS partition for windows, the Ext-4 partition for Ubuntu 10.04 Netbook Remix, and a large NTFS partition for my all my media. I installed the netbook remix off of a flash drive, and I couldn't have asked for a smoother install. Everything went fine, and I proceeding to install google chrome and all the other little goodies. After that, I configured all my settings and ran the update manager to get everything just fine. After a reboot, I became frustrated and prevented maximus from running on start up because I did not want every windows I opened to be maximized. After a reboot, the screen would flash very brightly more than once per second. I could see the top bar with the processes and such as well as the correct background, but I cannot do anything because the screen will not stop flashing. I figured out I could stop it from flashing by pressing ctrl+alt+F7, but the screen just freezes where it is at and is still unusable. Desperate to start enjoying my Ubuntu Netbook Remix, I wiped the Ubuntu partition and reinstalled and did everything EXACTLY the same except instead of preventing maximus from opening, I used gconf-editor to change the setting to not maximize everything by default. Reboot, exact same problem.
I've searched everywhere for a solution, but I only find people with vague similarities or explanations. Could it possibly be a graphics problem? My laptop has 2 graphics cards in it - an Intel integrated one and an nVidia one. The nVidia one has a hardware issue so I just use the Intel one for now. It is also worth noting that I have installed Ubuntu 10.04 (desktop) on my machine before and I never had any such problem.
Also, I tried booting up in the "safe mode" equivalent, but I eventually encounter a black screen and I am forced to hold down the power button to shut it down.
(also, if it's worth anything, I know how to use windows well if there's any way I can change something in Ubuntu from my windows installation)

when I install them all goes well but when I get into the GUIs I can hardly press anything - major bug with mouse and it is really annoying. Secondly there is a big gap between the GUI and my screen's edge. Hmm, I think - it must be a problem with the GPU driver and that might be the thing also messing with the mouse clicks. I download the drivers provided by the Ubuntu community - all goes well and I restart - stuck at purple screen after the "moving dots" on boot. So I reinstall the whole OS and try with the drivers provided by NVIDIA - same thing. I try the same procedure with Kubuntu and no progress.

I'm running 9.10 with a Radeon X300 video. Two displays, one is 1920x1200, the other is 1600x1200. I'm finding that some apps don't like to be too far to the right (anything past about 2600 x-resolution). If I move a window that far to the right, some of the controls are blank. A good example is OpenOffice. If I move an OO app too far to the right, the text in the main menu items will all be blank. All I see are the icons and the underscores for the keyboard shortcuts. There are other apps that do it, but OpenOffice is the most popular.
I tried re-configuring my displays, and it is always the one on the right. If I stack them top-to-bottom, I don't see the problem. If I reduce resolution, the problem diminishes, until I reduce the total x-resolution to below about 2600.

I require the use of two apps that appear to have similar problems and am wondering if they stem from the same problem. Both have been installed from .deb files and are not part of the official repos.The first is OpenCPN which, when installed, creates a menu entry. The the initial splash screen displays but after clicking OK, nothing appears at all.The second is Inform 7, which was working fine for a couple of days. Now the Game tab is empty. This is the tab that renders a version of the final game whilst working on it.Without knowing the two apps I realise it is difficult to get an understanding of what is wrong with them but it seems to be my machine that's at fault, not the apps as apparently they run fine on other people's machines.What checks can I do to get to the bottom of these problems?

Just installed Ubuntu 9.10 side by side with XP. When trying to run ubuntu from Grub the terminal screen opens but then starts to flash. This makes it difficult to type and login. When I do eventually login it just goes no further than a terminal prompt.If I use recovery mode the screen does not flash but still cannot get to the desktop

When I try and install Ubuntu 9.10 it gets to the flashing Ubuntu logo, then the screen just goes black. It then says: (initramfs) Unable to find a medium containing a live file system. I also tried the disk on a another computer and it worked fine, and I've installed Ubuntu 7.10 on this computer before without a problem.

I've installed Ubuntu 10.10 Netbook to my sisters laptop (Dell Latitude C640) but there appears to be a problem with the screen going black then opening the primary window, then loading the sidebar and then going black again.
For example, I'll hover over the new bar on the left and it'll just disappear, the screen will go black then will suddenly come to life again and then disappear, go black and so on. It just cycles through that.
