Description John Reiser 2005-05-04 11:08:32 EDT
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux ppc; en-US; rv:1.7.7) Gecko/20050416 Fedora/1.0.3-2 Firefox/1.0.3

Description of problem:
[PowerPC Mac mini]  Attempting to switch from X11 graphical console to character virtual console via Ctrl-Alt-F2 gets DPMS Suspend Mode only, and no virtual console.  Switching back to graphical via Ctrl-Alt-F7 does work.  mingetty is running:
# ps ax | grep getty
 2197 tty1     Ss+    0:00 /sbin/mingetty tty1
 2198 tty2     Ss+    0:00 /sbin/mingetty tty2
 3346 pts/0    S+     0:00 grep getty

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. log in to X11 graphical
2. Ctrl-Alt-F2 to switch to virtual console

Actual Results:  Monitor goes to DPMS Suspend Mode, and no virtual text console.  Switching back to graphical via Ctrl-Alt-F7 works.

Expected Results:  Change to virtual text console.

Additional info:

kernel is  2.6.11-1.1282_FC4.

fwiw, I can't repeat this in FC4t3, on similar hardware. This is actually
sitting in fd.o bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=3280

I've posted information of possible "diffs" that original bug reporter can take
a gander with, to see if it will fix the issue or not.

Can you try xorg-x11-6.8.2-45 ?
Comment 3 John Reiser 2005-08-12 20:11:05 EDT
With xorg-x11-6.8.2-45 (which required glibc-2.3.90-8 from yum) I got X11
graphical display at 800x600 with depth 16.  This was after booting to single
user mode, then "telinit 3", then "telinit 5".  I added 1024x768 to the front of
the list, logged out, restarted the Xserver with Ctrl-Alt-Backspace, and got
1024x768.  So, that was success for a while.  However, upon rebooting, the X11
graphical display would not start: "no screens found" in one log file and
"screens found, but none have a usable configuration" in another log file.
Trying to [auto] re-configure the Xserver did not work, and eventually GDM got
shut off.  Rebooting once more failed to bring up X11 graphical display, despite
going through the whole process of reconfiguring.  End result is no X11 graphics
at all, though it was "working" for a while.

Kernel is 2.6.12-1.1398_FC4 (July 15); PowerPC 32 (Macintosh Mini, radeon 9200.)
Comment 4 Olivier Baudron 2005-08-13 02:03:50 EDT
Can you attach /etc/X11/xorg.conf and /var/log/Xorg.0.log ?

System became unstable: <Enter> at shell prompt got "Segmentation violation". 
Booting single user hangs just after messages about duplicate mknod of
/dev/console, /dev/null, /dev/tty.  I suspect glibc-2.3.90-8.  The previous 2
attachments were obtained by booting from rescue CD-ROM (Ubuntu 5.04 Live),
mounting the Fedora Core root partition, and scp to another machine.

Comment 10 Florian La Roche 2006-05-10 09:57:24 EDT
This does not seem to be a bug report against mingetty, so I am closing this
bug report here. Please reopen against another component if you want to have
a patch applied for some other component.
