After running Xserver 220.127.116.11 for an extended number of hours after a fresh computer boot, doing ctrl+alt+f1 results in a blank screen (for example, the monitor says 'no signal').
I can easily do ctrl+alt+f7 and get back into my gnome session.
Another thing is that after I do ctrl+alt+f1, despite the fact that the screen is blank, I can still blindly log into that virtual terminal, do some operations and log out (which means the computer is not frozen).
I've seen this on two computers, one running open source Intel display drivers and another one running nvidia proprietary drivers
Also restarting the xserver by doing ctrl+alt+f1 then blindly logging in as root, and running: init 3 ; rmmod nvidia ; init 5 ; exit doesn't solve the problem and vt(1-6) are still blank.
This isn't just an nvidia issue, this also happens on my laptop at random events when shutting down: 50% of all cases I get a blank screen during shutdown.
MSI Megabook S262B, Core Duo T2050, Intel 945GM, screen detected as LVDS
xorg-server 18.104.22.168, kernel 2.6.22-rc5, xf86-video-intel 2.0.0, mesa 6.5.3, stock kernel DRM drivers
Sometime simply restart Xserver 22.214.171.124 by doing ctrl+alt+backspace causes this breakage.
Still happens under xserver 1.4 and mesa 7.0.1
1. Start X server and log in to gnome.
2. Suspend the computer to disk ( hibernate).
3. Resume from hibernate and restart Xserver. VT(1to6) is now broken.
The problem seems to only happen after restarting the Xserver
I can still start separate working X sessions under the broken VTs but once I exit them, the VT is still broken again.
For some reason, restarting X server after resuming from suspend breaks the VT. It's really getting hard to investigate why this is happening. Any help from Xserver experts is more than appreciated.
Steps to fix:
1. Run CTRL+ALT+F1.
2. It's blank so I have to blindly type in stuff.
3. Type root and enter the root password.
4. Run init 3 to exit Xserver.
5. At this moment, I'm blindly typing in stuff because I only see a blank screen.
6. Run pm-hibernate or any other hibernate script.
7. Resume from hibernate.
8. Virtual terminals are no longer blank (I can see again).
It seems to have been fixed in xserver 1.4.1 and it still works in 1.6.1
so I'm closing it. Sorry for the massive delay in closing the bug :)
