Binary package hint: xserver-xorg
When I first installed Lucid on my T500 I believe everything seemd to be fine with the display. Recently though the screen has started giving flashes -- as though there was some form of sync problem for the display. The flashes are of irregular frequency and occurrence. I haven't yet seen any pattern to the behaviour. They are however exceptionally annoying.
I believe I am using the Intel chipset graphics device -- I am not actually aware of how to switch to using the alternate graphics hardware, but I am told it is not worth bothering with, so I haven't.
I am using the Compiz window manager so I guess the problem could be there rather than with Xorg.
There is no xorg.conf file so there is no overide of the default behaviour.
I am not sure what programs to run to give useful output for this problem. I have attached the current Xorg log file. |

[Workaround]
As workaround add the option i915.powersave=0 to the kernel command line in the grub config (for GRUB 2: edit /etc/default/grub and add i915.powersave=0 to GRUB_CMDLINE_LINUX, then run sudo update-grub; for GRUB 1: edit /boot/grub/menu.lst and add i915.powersave=0 to the end of the line beginning with # kopt=, then run sudo update-grub).

I am using the Compiz window manager so I guess the problem could be there rather than with Xorg.
There is no xorg.conf file so there is no overide of the default behaviour.
I am not sure what programs to run to give useful output for this problem. I have attached the current Xorg log file.

[Workaround]
As workaround add the option i915.powersave=0 to the kernel command line in the grub config (for GRUB 2: edit /etc/default/grub and add i915.powersave=0 to GRUB_CMDLINE_LINUX, then run sudo update-grub; for GRUB 1: edit /boot/grub/menu.lst and add i915.powersave=0 to the end of the line beginning with # kopt=, then run sudo update-grub).
[Report]
Binary package hint: xserver-xorg
When I first installed Lucid on my T500 I believe everything seemd to be fine with the display. Recently though the screen has started giving flashes -- as though there was some form of sync problem for the display. The flashes are of irregular frequency and occurrence. I haven't yet seen any pattern to the behaviour. They are however exceptionally annoying.
I believe I am using the Intel chipset graphics device -- I am not actually aware of how to switch to using the alternate graphics hardware, but I am told it is not worth bothering with, so I haven't.
I am using the Compiz window manager so I guess the problem could be there rather than with Xorg.
There is no xorg.conf file so there is no overide of the default behaviour.
I am not sure what programs to run to give useful output for this problem. I have attached the current Xorg log file.

[Alternative workaround for experts]
Compile your kernel with Andy Whitcroft's patch from http://people.canonical.com/~apw/lp538648-lucid/ (see comment #88).

Binary package hint: xserver-xorg
When I first installed Lucid on my T500 I believe everything seemd to be fine with the display. Recently though the screen has started giving flashes -- as though there was some form of sync problem for the display. The flashes are of irregular frequency and occurrence. I haven't yet seen any pattern to the behaviour. They are however exceptionally annoying.
I believe I am using the Intel chipset graphics device -- I am not actually aware of how to switch to using the alternate graphics hardware, but I am told it is not worth bothering with, so I haven't.
I am using the Compiz window manager so I guess the problem could be there rather than with Xorg.
There is no xorg.conf file so there is no overide of the default behaviour.
I am not sure what programs to run to give useful output for this problem. I have attached the current Xorg log file.

[Status]
Fixed in maverick
Not fixed in lucid (bug still seen on 2010-09-22 with kernel 2.6.32-25)
[Workaround]
As workaround add the option i915.powersave=0 to the kernel command line in the grub config (for GRUB 2: edit /etc/default/grub and add i915.powersave=0 to GRUB_CMDLINE_LINUX, then run sudo update-grub; for GRUB 1: edit /boot/grub/menu.lst and add i915.powersave=0 to the end of the line beginning with # kopt=, then run sudo update-grub).
[Alternative workaround for experts]
Compile your kernel with Andy Whitcroft's patch from http://people.canonical.com/~apw/lp538648-lucid/ (see comment #88).
