Red Hat Bugzilla – Bug 217352
Switching virtual terminals breaks X on G965
Last modified: 2007-11-30 17:11:50 EST
Description of problem:
Switching from X to a text-mode virtual terminal and back to VT7 results in a
blinking single-color screen on VT7. Re-starting X doesn't help, the only way to
restore normal X display is to reboot.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
Blinking blank screen
Normal X user interface
Intel DG965WH motherboard, Core 2 Duo E6600 processor.
Adding Option "VBERestore" "true" to xorg.conf seems to fix the problem.
I have the same behavior with Intel DG965SS motherboard and Pentium D 2.8 Ghz.
The tip from comment #1 does not work in my case.
Thanks for the bug report and sorry for so late reply to it.
Please attach your X server config file (/etc/X11/xorg.conf) and X server log
file (/var/log/Xorg.*.log) to the bug report as individual uncompressed file
attachments using the bugzilla file attachment link below.
Could you please also try to run without any /etc/X11/xorg.conf whatsoever and
let X11 autodetect your display and video card? Attach to this bug
/var/log/Xorg.0.log from this attempt as well, please.
We will review this issue again once you've had a chance to attach this information.
Thanks in advance.

I confirm the bug. Flickering screen results, when one switch to console and
back. "VBERestore" option does not help

Xorg.0.log with modesetting driver
I've played around with it a bit, and the modesetting driver branch ("intel"
instead of i810) successfully resets the display and works well when switching
bewteen VTs and the X session. This is with xorg-x11-drv-i810-1.6.5-11.fc7
(x86_64). Attached is my Xorg.0.log file with this driver instead of i810.
intel driver is the default now for 965 hardware, so marking this one as fixed
