xorg.conf

Fonts are corrupted (look like little blocks) when I switch back to X from a
virtual console. Restarting X is the only solution.

Reproducible: Always with .903, not with .902 or .901

Steps to Reproduce:
1. Switch to virtual console and make some output occur (e.g. dmesg)
2. Switch back to X with Ctrl-Alt-F7

Actual Results:  
Fonts are corrupted, can't read anything.

Expected Results:  
Non-corrupt fonts.

Comment 3 Gordon Jin 2008-04-21 01:34:04 UTC

Increasing priority as this is 2.2.99.903 regression.

Comment 4 Wang Zhenyu 2008-04-21 02:04:03 UTC

I can't produce on Lenovo T61 here, in gnome switch vt, X came back normally.
Could you try current 2.3-branch? or could you nail down what change might cause this? (try options like "Tiling" "EXANoComposite", etc.)

Comment 5 Aike J Sommer 2008-04-24 06:31:31 UTC

I had the same problem... EXANoComposite fixed this!!
:-)

Comment 6 Wang Zhenyu 2008-04-24 17:45:06 UTC

Aike, what's the model of your machine? Have you seen this corrupt before (like 2.2.1) or just recent 2.3.0? Possible to try 2.2.99.901~903 to see if that's regression?

EXANoComposite seemed to fix it. Is that a boolean? It doesn't matter whether I set it true or false, it fixes it either way.

Only occurs on 903 for me, 902 and 901 are fine.

Comment 8 Aike J Sommer 2008-04-25 00:19:08 UTC

It's a Dell XPS M1330...
I have this with all versions i tried, being 902, 903 and 2.3.0 (and whatever opensuse 11.0 beta 1 installed as default).

Comment 9 Wang Zhenyu 2008-06-18 01:23:35 UTC

Could you test with current 2.3.2 release?

Comment 10 Aike J Sommer 2008-06-18 04:03:13 UTC

Just tested it, and it seems to be fixed for me!!
:-)
