Corrupted display

This is the photo of the corruption

Please attach `hwinfo --gfx' as well as your /etc/X11/xorg.conf /var/log/Xorg.0* logs. Does the framebuffer work correctly? In that case, does it work correctly when booting with vga=normal?

I think that framebuffer works correctly. well all works correctly when booting up. It is just on shutdown that display gets corrupted. I'm not sure how to see only for framebuffer if it works correctly. I'll try with vga=normal and see how it goes.

How did it go?

Sorry for the late response.

I used the vga=normal kernel option and all was working just fine. If I don't count that the boot and shutdown splash didn't show up. But other then that, no corruption.

Of course they would not show up in ASCII mode ;)
OK - are you sure that your X11 display and the used framebuffer mode have exact the same resolution and color depth? On some gfxcards, specially those with shared memory, problems of this sort occurr - there is no real fix for that.

Check this and try it again, it should work.

All resolutions were automatically set up during installation. I know that X uses 1024x768 24-bit, But I don't know how to check this for framebuffer.

It's encoded in the vga=... mode number as follows:

Resolution in pixels
Color depth      |   640x480      800x600      1024x768      1280x1024
256        (8bit)|     769          771           773           775
32000     (15bit)|     784          787           790           793
65000     (16bit)|     785          788           791           794
16.7 Mill.(24bit)|     786          789      -->  792           795

For you this would mean using mode 792
Set it up in /boot/grub/menu.lst (you can use YaST and expert configuration) or at first just try it by just applying the parameter as boot-append line.

This is what installation set for me in /boot/grub/menu.lst

vga=0x317

I'll try to reboot and use vga=792 and see how it goes.

Well I tried with vga=792 but now I don't get any nice boot splash on bootup, only high res text boot, and on shutdown I still have corrupted display.

so it works with vga=normal.

closed, but put maintainer into cc:

Stefan: reopen if you want.

If I run with vga=normal there is no boot/shutdown splash and it is just a workaround. Why is this not going to be fixed to work properly?

This bug is the same bug as #160833 !

Use "vga=791" for splash.
