[Bug 1098334] Re: [gen4 sna] Font corruption
After reading this page https://downloadcenter.intel.com/product/81523 /Graphics-Drivers-for-Intel-82Q963-Graphics-and-Memory-Controller-Hub- GMCH-, I see that latest official drivers from Intel date from august 2013. Possible workarounds: - Keep on using Linux and have to reboot every few hours to see text ok - Install Windows, even though I prefer Linux. - Buy another computer. (I don't like to do so, in an otherwise good working computer). - Try to use another driver. Which one? $ lsmod Module Size Used by i915 783805 2 video 19476 1 i915 I think the used driver is i915. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1098334 Title: [gen4 sna] Font corruption To manage notifications about this bug go to: https://bugs.launchpad.net/xserver-xorg-video-intel/+bug/1098334/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1098334] Re: [gen4 sna] Font corruption
I've found a relevant document about our bug: There are a couple of backends available for accelerating the DDX. "UXA" (Unified Acceleration Architecture) is the mature backend that was introduced to support the GEM driver model. It is in the process of being superseded by "SNA" (Sandybridge's New Acceleration). Until that process is complete, the ability to choose which backend to use remains for backwards compatibility. SNA is the default acceleration method in xf86-video-intel. If you are experience issues with SNA (e.g. pixelated graphics, corrupt text, etc.), try using UXA instead, which can be done by creating an X configuration file containing the following: /etc/X11/xorg.conf.d/20-intel.conf Section "Device" Identifier "Intel Graphics" Driver "intel" Option "AccelMethod" "uxa" EndSection Source: https://wiki.archlinux.org/index.php/Intel_graphics#SNA_issues So, I've created a file called 60-patch-graphis.conf in the /usr/share/X11/xorg.conf.d folder, and reboot my system.

Jonathan Thomas, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please test for this with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ .

For me #define MAX_FLUSH_VERTICES 1 fixes the issue. #define
MAX_FLUSH_VERTICES 2 is also stable so far. Values starting from 3
result in artifacts.
However, as I wrote in post #150, reverting this:
diff --git a/src/sna/sna_glyphs.c b/src/sna/sna_glyphs.c
index 62415c8..43086a0 100644

-(sna-kgem.gen 3) != 4) { /* XXX cache corruption? how?

+ if (this_atlas-format == (format-depth 24 |

Solves the problem at all - even setting #define MAX_FLUSH_VERTICES 128
works correct, as well as #define FORCE_FLUSH 0 is also fine.
