Public bug reported: Today a new release of the intel driver was released. this will fix a lot of problems. it will fix the xorg-crash after closing of minecraft in ubuntu for example and much more -
Please upgrade to this version or backport the fixes. Release 2.19.0 (2012-04-29) =========================== More stability fixes for UXA and support for another variant of IvyBridge. Given the severity of the stability fixes, I strongly recommend everybody to upgrade to 2.19.0. -Chris * Prevent waiting on scanlines whilst not in control of the VT and therefore whilst referencing foreign CRTC configurations. * Pixmap (and bo leak) during fallback glyph composition * Remove broken acceleration for rendering glyphs directly upon the destination pixmap, exposed by cairo-1.12.0 (and coincidentally fix another Pixmap leak upon fallback handling). * Add support for Ivy Bridge GT2 Server chipset [PCI id 0x016a] * Remove broken damage flushing with CompositeRectangles https://bugs.freedesktop.org/show_bug.cgi?id=32547 * Fix crash upon server start with multiple monitors https://bugs.freedesktop.org/show_bug.cgi?id=47395 * Fix composition issues resulting from overly aggressive Pixmap reuse https://bugs.freedesktop.org/show_bug.cgi?id=47345 Chris Wilson (229): legacy: Delete unused XF86DRI_DEVEL #define legacy: Rename XF86DRI to HAVE_DRI1 to avoid conflicts with xorg-server.h sna: Skip a tiled bo when searching the cache for a linear mmap sna: Ensure we trigger a retire for search_linear_cache sna/gen3+: Keep the vertex buffer resident between batches sna: Retain unfinished partial buffers between batches sna: Avoid reusing mmapped partial write buffers for readback meh sna: Upload the ordinary partial buffers!
