xorg config
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? Can you attach your X log too? 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... "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. 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 Both startx & X+xterm+twm can reproduce this bug , when using 2.3.0 . (In reply to comment #6) > Gordon, I'm able to reproduce this with stock 2.3.0 as well.

The LVDS breakage only impacts 855gm, not 915gm, right? On the other side, I remember we've validated VT switch ok on 2.2.99.902. Lerui, please bisect starting there.

>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? 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). 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. 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... Created attachment 16515 [details]

When I switch to the KDE , sometimes , the font is missing, you can see IMG_0096.jpg above . 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. It runs fine on latest Xf86_intel_video master tip, as you know the 2.3.0 branch has been merged into the master. Rocco, I can't reproduce the "text disappears" problem anymore, can you? Nope, the new driver seems to work fine. Thanks |

Created attachment 16268 [details] kernel config Just updated to the new intel driver i810.2.3.0. Everything seems to work fine in xorg but when I switch back to shell using ALT+... the screen blanks. Actually it seems one of the old virus, the one deleting word by word everything that was on the screen.
