View Full Version : [ubuntu] Screen flicker on shutdown and reboot

September 17th, 2009, 01:14 AM
I have Ubuntu 9.04 32-bit running on a Toshiba Satellite M305-S4910. Recently I disabled the bootup splash screen from grub and ever since whenever I shutdown, reboot, and sometimes when I go into a console (by pressing CTRL+ALT+F1) the entire screen flickers and at the top of the screen there is cropped text also flickering. I would like to keep my grub configuration as it is but this is really annoying, is there anyway to solve it?

I'm having a similar issue, but I did not disable a bootup splash screen for grub. I am running Ubuntu server 9.04_64. When I boot with the option vga={any vga mode here} the screen flickering is on only the grub screen, but if I boot without that option the screen flicker exists on all of my tty's.

My motherboard is a d945gclf2 and it has no flicker problems on the POST splash screen or POST information screen.

When it is flickering in grub and tty the monitor reports:


however when I use the screen on another computer running Ubuntu Desktop it reports

(The correct and maximum resolution for the monitor)

I have noticed that if I go into the console (CTRL+ATL+F1) it flickers as usual but if then I go back into GDM (CTRL+ALT+F7) and then shutdown/restart it won't flicker.

I also have the same problem.

I'm running Ubuntu 9.04 on an Acer Aspire 4520 (Nvidia 7000m, proprietary drivers 180.x). My screen goes black at the center with white around the edges, and a LOT of flickering. This happens when I switch consoles (Ctrl-Alt-<function key>) and also during the shutdown process (I can't see the shutdown splash).

I hope someone can help out. Thanks!

Does the screen flicker while in the GUI? It probably has something to do with refresh rate. I don't know how to go about your problem, but at least I'll give you a possible lead.

i am using windows xp Since the install my screen has been constantly flickering. I tried all the usual suspects. I updated the video card driver, and even went to the nvidia website to get the lates 64x vista compatible driver. I lowered my screen resolution, and refresh rate. Nothing worked.

I updated to 9.10 and the flickering stopped.
