I strongly believe that the big average of the users who are having this same problem are unable to find this page (since the issue is hard to explain) and are thus unable to workaround the issue. I myself have spent 2 days searching - which speaks for itself, doesn't it? So even if the package maintainers only decide to automatically activate DebugWait on these cards by default it would be a great improvement that would solve all future problems.There should be enough code already present in the automatic configuration detection logic of Xorg to add this small check with a few lines of code. Though, I'm not a package maintainer nore do I know how it works. Thus my estimates are surely not the best. All summed up: just hack it so that it works for the masses.

(Subscribing dpsenner to this bug) Dominik: It's cool when you find a bug report that might help you fix a problem isn't it? :-) Speaking as a random person on the Internet (I don't work for Canonical, Intel etc), it's very unlikely that you can have a bug's priority raised by asking (although subscribing/marking a bug as also affecting you is useful as it makes it clear how many people are interested in a given bug). The general reason is that while the bug may be massively disruptive for you, there are finite resources to go into fixing problems. If more people are seeing another issue just as major or more significant in some manner, then it is likely the resources will be put into solving that issue. Of course, I would like to see this particular bug resolved too :).

To answer Ferry's question about why the fix works: one of the Intel developers mentioned that this era of graphics cards have constraints related to tiling and DebugWait disabled tiling entirely (but another issue meant that Tiling false did not disable tiling(!)). It was only in later versions of the X drivers that tiling was actually used tiling, so that's why users with old Xorgs don't see this issue. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/745608 Title: [915GM] font corruption on Intel GMA900 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/745608/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Sitsofe: I reported the bug on my i945 with the desktop etc corruption at https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video- intel/+bug/820881 However I suppose the bug on my i915 is the same one as described here, because I see mainly font corruption. Window buttons are a small exception which is quite hard to notice, but this was also reported in the original bug report on i915. I believe these reports belong together, because they both consist of similar defects (extra vertical lines on small sprites). Or do you suppose there should be also separate bug report on window buttons for i915?

[Bug 745608] Re: [915GM] font corruption on Intel GMA900
I installed the update package 2:2.14.0-4ubuntu7.2 from natty-proposed and it seems to make things better. At least on my laptop (915/910) I haven't noticed corruption since upgrading the package (but this may change in time, I cannot be sure). But it's different on my desktop (945), where the new package probably reduces the problem, but it still appears in previous form after some time. When I set Tiling=false it reduces corruption a lot, but there still appears some like before. Although I did notice it only in Ubuntu menu bar (submenus were fine). When I set DebugWait=true instead of Tiling=false, some of the games started doing a lot of hiccups and were practically unusable (I tried teeworlds from GetDeb). Some corruption appeared but was very episodical, by now I have noticed it only on GDM logon background image. I'd say, for me Tiling=false seemed a better workaround, because it didn't ruin the gaming experience and I didn't notice too much slowing down. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/745608 Title: [915GM] font corruption on Intel GMA900 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/745608/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 745608] Re: [915GM] font corruption on Intel GMA900
Ferry: I actually don't know why it works :) Sadly I didn't get to that option by logical deduction but rather by trying everything I could... My guess is that there is a race happening where a buffer is being reused while it actually still in use. Here's what the intel man page says about the DebugWait option: Option DebugWait boolean Wait for the completion of every batch buffer before continuing, i.e. perform synchronous rendering. Default: Disabled So this changes from submitting batch buffers and *not* waiting for a reply to waiting for a reply after submitting each batch buffer (so effectively you can no longer simultaneously submit multiple batch buffers). This should also hurt speed as it is no longer possible to do so much at once so it's strange you are seeing a speed improvement... There is also some slight evidence that this is a locking issue. Over on https://bugs.freedesktop.org/show_bug.cgi?id=36326#c8 I tried to find why certain old kernels don't show the issue and that narrowed down it down to a patch that removed the Big Kernel Lock (BKL) from various functions of the i915 driver presumably allowing more overlap. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/745608 Title: [915GM] font corruption on Intel GMA900 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Screenshot: https://bugs.freedesktop.org/attachment.cgi?id=45730 A rectangular/square block of the glyph is missing. Affects the same character of that font/size repeatedly, problem persists past a repaint. Probably the same as the above but might be different. Tends to be rarer than the first type of corruption.

Another thing to check is whether turning off tiling by putting Section Device Identifier Intel Driverintel Option Tiling false EndSection in /etc/X11/xorg.conf and then rebooting changes whether the corruption appears (the above is purely for testing purposes though - don't run daily with such a configuration as it will be very slow!). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/745608 Title: [915GM] font corruption on Intel GMA900 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Sitofe, Currently on my eeepc I see these both problems sporadically, but it is very workable, so I don't dare to complain. I have had these same corruptions on the eeepc before. It seems to be coming and going with linux releases. On the desktop with 945G at times ff becomes unreadable, until I press increase font size 2 times (ctrl-+). Both problems you mention can be observed (exactly as you say, it affects a certain character/font/size combination, and eventually more and more become broken, switching to another size/font temporarily solves the problem), but the font problem is the most common and disturbing. Note that while some complain about their terminal program, I don't see it in konsole (KDE terminal). This may be due to the font used?

Yes, and no. I'm not using a dutch localization, so you I don't normally have Cyrillic fonts :-) Also I'm using Kubuntu (though with evolution). But both on Eeepc and 945G the problem is that fonts are broken. Each broken letter shows the same distortion as shown in screenshot $1 (where the 'e' is broken).

Given how badly readable the display is on 82945G I would say the importance should be higher then 'low'. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/745608 Title: [915GM] font corruption on Intel GMA900 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 745608] Re: [915GM] font corruption on Intel GMA900
No, on one system I never suspend. It seems more related to the time an application or the system is running. BTW it also occured on Debian Squeeze with kernels earlier then 2.6.38. I am not sure but I think it got introduced with the intel driver 2.14.

Yes I have it too on Eepc 900 and also on desktop with 'Intel Corporation 82945G/GZ Integrated Graphics Controller (rev 02). All with Kubuntu. See attachment following. Had the same in Debian Squeeze. (same driver I guess, and older KDE). Do not see the problem on Natty Kubuntu with Nvidia card.

Sorry for asking again, but do you have natty-updates enabled and 2:2.14.0-4ubuntu7.1 installed that you can test again with?

Yes, I have natty-updates enabled and 2:2.14.0-4ubuntu7.1 installed. The above screenshots were with the latest packages (natty-proposed not enabled). I looks like the longer I have an application running the more distored the fonts. I can hardly read what I'm typing right now. Could it be related to some font cache?
