Public bug reported:
Binary package hint: xorg
Using the Intrepid Alpha 4 LiveCD on my Vaio VGN-SZ71WN, the display
comes up black at GDM stage. Ctrl-Alt-F1 causes some flickering of the
backlight, but no prompt comes up, the screen remains black.
Using the "safe graphics" mode of the LiveCD allowed me see the screen
(although the resolution was recognised by VESA as 1024x600 instead of
1280x800). I than installed to disk and installed all updates.
However still now when booting from the hard disk I am getting the same
small resolution in the middle of the screen and its using the VESA
driver rather than the intel one. Attempting to switch xorg.conf from
"vesa" to "intel" didn't help either.
I then noticed some settings on the grub kernel line:
title Ubuntu intrepid (development branch), kernel 2.6.26-5-generic
root (hd0,8)
kernel /boot/vmlinuz-2.6.26-5-generic
root=UUID=34dd755c-709a-4ee3-a4a5-f2e2f30d6587 ro xforcevesa quiet splash
initrd /boot/initrd.img-2.6.26-5-generic
quiet
Most notably "xforcevesa". Is this put in place purely because the
LiveCD was booted in safe graphics mode? This "xforcevesa" setting is
also found on the "# kopt=" line.
Removing "xforcevesa quiet splash" from the end of the boot line in grub
allowed me to boot up and correctly use the intel driver.
So the driver works, but Xorg seems unable to detect and configure it
correctly.
