xorg.conf (in working XAA mode)
I can reproduce it here, with xmgrace: the fonts in the graph are shown as black noisy squares. However, I cannot notice this in any other program. GTK and QT programs work fine. xedit, xmag are fine as well. The widgets of xfontsel are displayed correctly, however, it doens't show any font in the font display (but I haven't checked if in XAA it works). I also have a 64bits computer with server 1.5.3 (on Mandriva cooker). Driver is intel 2.5.1, with a : 00:02.1 Display controller: Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (rev 0c) Unless this can be reproduced with other drivers, it's probably a driver issue. I don't know about other applications (?) mentioned in the original report, but the problem with xmgrace is not a font issue at all. See latest comments to <https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/325169>. Hopefully the simple demo attached will help you tracking the bug down.

Yes, simple demos to reproduce bugs are usually very helpful. Does this xserver patch fix the demo/xmgrace with EXA? Yes it does, thanks - great & fast work! Can you please explain why only Intel hardware is affected? (In reply to comment #6) > Yes it does, thanks - great & fast work! Well, it's not the final fix yet - there are other places which need the same treatment. > Can you please explain why only Intel hardware is affected? Doesn't look like that's the case after all. (In reply to comment #7) > Doesn't look like that's the case after all. Yeah, the patch is generic; but can you reproduce the bug with any other driver? All reports I've seen so far are from Intel-hardware owners: <https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/325169> <https://bugzilla.redhat.com/show_bug.cgi?id=484273> <http://plasma-gate.weizmann.ac.il/Grace/phpbb/viewtopic.php?t=1547> <http://plasma-gate.weizmann.ac.il/Grace/phpbb/viewtopic.php?t=1557> <http://plasma-gate.weizmann.ac.il/Grace/phpbb/viewtopic.php?t=1657> OK, there is now an evidence the bug affects other hardware, too: <https://bugzilla.redhat.com/show_bug.cgi?id=493131> *** Bug 19167 has been marked as a duplicate of this bug. *** i386 is also affected. NetBSD is also affected. Fix pushed to Git master and nominated for server-1.6-branch. |
