Public bug reported: Release: Ubuntu 15.04 (vivid) Package Version: 2:2.99.917-1~exp1ubuntu2build1
I'm experiencing a consistently reproducable segfault when attempting to use hardware acceleration. I've installed xserver-xorg-core-dbg and xserver-xorg-video-intel-dbg and attached the gdb log file. Additionally, here is the backtrace from the X log: Backtrace from /var/log/Xorg.0.log.old: [180619.415] (EE) Backtrace: [180619.415] (EE) 0: /usr/bin/X (xorg_backtrace+0x56) [0x7f27d5295556] [180619.415] (EE) 1: /usr/bin/X (0x7f27d50e2000+0x1b7749) [0x7f27d5299749] [180619.415] (EE) 2: /lib/x86_64-linux-gnu/libc.so.6 (0x7f27d2da8000+0x352f0) [0x7f27d2ddd2f0] [180619.415] (EE) 3: /usr/lib/xorg/modules/drivers/intel_drv.so (0x7f27ccf99000+0x6e544) [0x7f27cd007544] [180619.415] (EE) 4: /usr/lib/xorg/modules/drivers/intel_drv.so (0x7f27ccf99000+0x10cc20) [0x7f27cd0a5c20] [180619.415] (EE) 5: /usr/bin/X (0x7f27d50e2000+0x184d0c) [0x7f27d5266d0c] [180619.415] (EE) 6: /usr/bin/X (DRI2CopyRegion+0x8b) [0x7f27d526769b] [180619.415] (EE) 7: /usr/bin/X (0x7f27d50e2000+0x187ac3) [0x7f27d5269ac3] [180619.415] (EE) 8: /usr/bin/X (0x7f27d50e2000+0x580a7) [0x7f27d513a0a7] [180619.415] (EE) 9: /usr/bin/X (0x7f27d50e2000+0x5c29b) [0x7f27d513e29b] [180619.415] (EE) 10: /lib/x86_64-linux-gnu/libc.so.6 (__libc_start_main+0xf0) [0x7f27d2dc8a40] [180619.415] (EE) 11: /usr/bin/X (0x7f27d50e2000+0x4662e) [0x7f27d512862e] [180619.415] (EE) [180619.416] (EE) Segmentation fault at address 0xffffffffffffff00 [180619.416] (EE) Fatal server error: [180619.416] (EE) Caught signal 11 (Segmentation fault).
