Here is the /etc/default/grub menu for this machine. ** Description changed:
On 11.10 and earlier, if I used a default /etc/default/grub file, the - kernel would boot fine and X would run fine. After upgrading to 12.04 - today, I found that while lightdm would come up, after I logged into the - desktop X was horribly broken with flashing colors and the like. This - was my only clue in kern.log: + kernel would boot fine and X would run fine. This was true whether or + not I accessed the grub2 menu (ie, holding shift after the BIOS screen + goes away). + + After upgrading to 12.04 today, I found that after accessing the grub2 + menu, while lightdm would come up, after I logged into the desktop X was + horribly broken with flashing colors and the like. This was my only clue + in kern.log: Feb 1 14:12:58 harry kernel: [ 33.626782] [drm:drm_mode_getfb] *ERROR* invalid framebuffer id - So I rebooted to try the 11.10 kernel and I could login to the desktop fine with no problems. I noticed that I could not get the grub menu to show up however (I used GRUB_DEFAULT=2 in /etc/default/grub in order to boot into the 3.0.0 11.10 kernel), so I started playing with GRUB_GFXMODE. 'vbeinfo' told me the recommended setting should be "1024x768", so I tried that with no change (ie, I couldn't see the grub menu). I then used: - GRUB_GFXMODE=640x480 + If I do not access the grub2 menu, I can login to X and everything is + fine. - and rebooted. This time I was able to see the grub menu. So I changed - back to GRUB_DEFAULT=0, ran update-grub and rebooted into the 12.04 - 3.2.0 kernel. At this point I was able to login to the 12.04 desktop - with the 3.2.0 kernel with no errors in kern.log. + I verified that booting into the 11.10 kernel on precise works as + expected: I can login to the desktop whether I access the grub menu or + not. - It appears that my hardware is reporting that 1024x768 is what should be - used, presumably defaulting to it and then not being initialized - correctly/working right with the new kernel and X stack. - - At this point my system is in good order, but this was a very bad - upgrade experience in general. + This will be a problem for anyone who is not using the default installed + kernel (eg testing, booting into a known-good kernel). The workaround is + to adjust /etc/default/grub and set GRUB_DEFAULT to the kernel you want + to boot into and run 'update-grub' (so we don't have to access the grub2 + menu).
