Red Hat Bugzilla – Bug 155530
X locks up the screen and keyboard on Ctrl+Alt+F7
Last modified: 2007-11-30 17:11:04 EST
Description of problem:
When the console is switched away from X and into the tty1 with Ctrl+Alt+F1, one
cannot go back to X with Ctrl+Alt+F7 on this particular hardware (I'll attach
lspci -vv later on). When Ctrl+Alt+F7 is pressed, the screen changes to a
somewhat garbled X session (i.e. it appears as if the session is there, but
there are garbled pixels at various places of the screen) and the keyboard and
screen lock up after that. One can SSH into the box fine.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Start X (GDM will do).
2. Go to tty1 by pressing Ctrl+Alt+F1.
3. Attempt to go back to X by pressing Ctrl+Alt+F7.
4. The screen and keyboard lock up.
Should work fine. And it did before X.org 6.8.2.
See attached lspci -vv. For hardware spec of this box go to:

This is DRI related. Disabled DRI and everything works fine. I'm guessing the
latest radeon driver additions for DRI of IGP chips are causing this.
Attach X server log and config file from after the problem, as well
as output of lsmod, sysreport, and /var/log/messages as individual
Setting status to "NEEDINFO"
Just tried Fedora Core 4, Test 3 on this machine. DRI enabled, but no problem
any more. Just downloading devel updates (new kernel, new X) - hopefully it
This is not fun anymore - all my bugs get fixed in new releases ;-)
I'll close once I confirm latest devel updates are fine too.
The X that's in Fedora Core 4, will eventually be released as an update
for Fedora Core 3. I might even release one to fc3-testing based from
it soon, to get some test coverage there.
So if the problem is fixed in FC4 currently, I think it's safe to close
this as "RAWHIDE" for now, knowing it'll be fixed in a future FC3 update
Thanks for the update.
Just checked with the latest X and kernel from devel - still good.
