Red Hat Bugzilla – Bug 231673
Virtual Console Switch corrupts graphical screen
Last modified: 2012-03-09 17:32:57 EST
Description of problem: Switch between tty7 and tty1 and back to tty7 results in corrupted single color waving screen. Killing X with Ctrl-Alt-BkSpc or changing runlevels does not resolve the issue, only a reboot returns a normal graphical screen Hardware: Dell Optiplex 745 w/ Intel Corp 82Q963/Q965 Integrated Graphics Controller How reproducible: Every single time Steps to Reproduce: 1. Switch to tty1 2. Switch to tty7 3. tty7 is corrupted, though able to return to usable tty1 Additional information: The vesa driver only helps mildly. With vesa it only corupts the screen about 30% of the time when switching. Repeated switching does bring back the graphical screen. Probably related to 217352 but this is in 32-bit environment.

I have just tested this with the 20070710 iso. While bug 217352 claims that we have switched to "intel" as the default, that does not appear to be the case as I continue to get "i810". I am still unable to switch consoles back to graphical mode in either anaconda, nor after the system is brought up.
Reporter, can we get your /var/log/Xorg.0.log from the X session when this happens, please?

(In reply to comment #2) > While bug 217352 claims that we > have switched to "intel" as the default, that does not appear to be the case as > I continue to get "i810". With already existing /etc/X11/xorg.conf we are keeping whatever was in the configuration file, moreover the bug you mentioned is against Fedora Core 6, which has different policy than RHEL. To test with intel driver, replace the section containing the line Driver "i810" with this Section "Device" Identifier "Videocard0" # or whatever else was there before Driver "intel" EndSection then restart X. If it breaks again, could please attach us new /var/log/Xorg.0.log to this bug as well, please?
Created attachment 195001 [details] Log from switching to the intel driver The intel driver (under 5.0) is not recognizing this card and so X is refusing to start at all.
Created attachment 195171 [details] Log under 5.1 with i810 driver This log is with xorg-x11-drv-i810-1.6.5-9.5.el5 and using the default detected driver from a "system-config-display --noui --set-resolution=1024x768" at the end of a kickstart %post under 5.1beta
Created attachment 195181 [details] Log under 5.1 with intel driver This log is with xorg-x11-drv-i810-1.6.5-9.5.el5 and using a hand edited xorg.conf that simply replaced the use of i810 with intel under 5.1beta
This appears to be fixed in 5.2 which autodetects and uses by default the intel driver rather than the i810 driver - so I would be OK with closing this.
Closing per comment #9, thanks!
