--- Begin Message ---Package: libcairo2 Version: 1.10.2-2 Severity: important Hello, upgrading libcairo2 to 1.10.2-2 crashes Xorg on a VIA VX800 Chrome 9 driven by openchrome when starting firefox (iceweasel) or gdm3 (it gets it managed to display the greeter and the bottom panel and crashes then). Xorg log excerpt: Backtrace: 0: /usr/bin/Xorg (xorg_backtrace+0x3b) [0x80ed75b] 1: /usr/bin/Xorg (0x8048000+0x587c5) [0x80a07c5] 2: (vdso) (__kernel_rt_sigreturn+0x0) [0xb78cc40c] 3: /usr/lib/xorg/modules/libexa.so (0xb71cc000+0xeedc) [0xb71daedc] 4: /usr/lib/xorg/modules/libexa.so (0xb71cc000+0xf5d8) [0xb71db5d8] 5: /usr/bin/Xorg (0x8048000+0xdbf2d) [0x8123f2d] 6: /usr/bin/Xorg (CompositePicture+0x200) [0x81151d0] 7: /usr/bin/Xorg (0x8048000+0xd4b11) [0x811cb11] 8: /usr/bin/Xorg (0x8048000+0xd1913) [0x8119913] 9: /usr/bin/Xorg (0x8048000+0x3a427) [0x8082427] 10: /usr/bin/Xorg (0x8048000+0x1e63a) [0x806663a] 11: /lib/i686/cmov/libc.so.6 (__libc_start_main+0xe6) [0xb75e1c76] 12: /usr/bin/Xorg (0x8048000+0x1e211) [0x8066211] Segmentation fault at address 0xc Fatal server error: Caught signal 11 (Segmentation fault). Server aborting Downgrading libcairo2 to 1.8.10-6 solves the issue: No crashes. This issue doesn't show up on a machine with Intel G35 driven by intel. I can't really tell how deep libcairo2 is involved into this, since upgrading to 1.10.2-2 also installs: libdrm-nouveau1a 2.4.23-0.0 libegl1-mesa 7.10-3 libegl1-mesa-drivers 7.10-3 libxcb-dri2-0 1.7-2 libxcb-shape0 1.7-2 libxcb-xfixes0 1.7-2 However, I have no idea how to narrow the issue down to one of them. regards Mario -- Independence Day: Fortunately, the alien computer operating system works just fine with the laptop. This proves an important point which Apple enthusiasts have known for years. While the evil empire of Microsoft may dominate the computers of Earth people, more advanced life forms clearly prefer Macs.
