Yeah, I've seen this too on 2.3, but the problem goes away if I exit the server. Do you see the same thing?
Comment 3 Jesse Barnes 2008-05-05 12:53:55 UTC
Can you attach your X log too?
Comment 4 Jesse Barnes 2008-05-05 13:16:42 UTC
Gordon, is this something you can reproduce & bisect? I was only able to reproduce it on my 855 after starting a full KDE desktop. If I start just twm & xterm then VT switch the fonts are fine, but after starting KDE then VT switching, the VGA fonts start disappearing...
Comment 5 Gordon Jin 2008-05-05 19:24:58 UTC
"switch back to shell with ALT+" actually means "switch back to text console with Ctrl+Alt+F1", right? Lerui, can you reproduce this on 915GM with the stable driver 2.3.0? Try KDE. If fail, then twn+xterm.
Comment 6 Jesse Barnes 2008-05-05 20:31:53 UTC
Gordon, I'm able to reproduce this with stock 2.3.0 as well. If you try bisecting, you'll run into the LVDS breakage I introduced with the panel fitting merge, so you'll need to hand apply the LVDS regression fix during each bisect phase. Thanks, Jesse
Comment 7 Colin.Joe 2008-05-05 22:32:24 UTC
Both startx & X+xterm+twm can reproduce this bug , when using 2.3.0 .

The LVDS breakage only impacts 855gm, not 915gm, right? On the other side, I remember we've validated VT switch ok on 126.96.36.1992. Lerui, please bisect starting there.

Yep, the problem goes way, or at least it seems to go away, I still haven't seen it when the server is down. >"switch back to shell with ALT+" actually means "switch back to text console >with Ctrl+Alt+F1", right? Yep

Lerui, when you reproduce this bug (switch to text console), it might be unstable and you might wait for about 10 seconds. And also notice if the fonts are ok when switching back to X (kde).
Comment 13 Colin.Joe 2008-05-06 23:51:03 UTC
I retested it on 915gm & 855gm, using 2.3.0, this bug can't be reproduced now, but when I switch from text console to KDE desktop, sometimes, its font is wrong draw.
Comment 14 Jesse Barnes 2008-05-07 09:58:27 UTC
Do mean the 2.3.0 branch? Can you capture a screenshot of the corruption you see when coming back from the text console? That may also match something I've seen...

When I switch to the KDE , sometimes , the font is missing, you can see IMG_0096.jpg above .
Comment 17 Jesse Barnes 2008-05-21 13:13:01 UTC
Rocco, I can't reproduce the "text disappears" problem anymore, can you? If so, please re-open. Colin, please file a separate bug for your "KDE fonts gone on EnterVT" problem, if you still see it with the latest bits.
Comment 18 Colin.Joe 2008-05-21 20:47:56 UTC
It runs fine on latest Xf86_intel_video master tip, as you know the 2.3.0 branch has been merged into the master.
Comment 19 rocco 2008-05-22 04:17:21 UTC
Rocco, I can't reproduce the "text disappears" problem anymore, can you? Nope, the new driver seems to work fine. Thanks
