Created attachment 14953 [details] log file I'm trying to run the latest Xorg server build with jhbuild, and all the dependencies and drivers are built from git versions too. It crashes with the following trace: Backtrace: 0: src/X/xorg/bin/Xorg(xf86SigHandler+0x79) [0x80b2c19] 1: [0xffffe420] 2: src/X/xorg/bin/Xorg(xf86OutputGetEDID+0x24) [0x80e56b4] 3: /home/vedran/src/X/xorg/lib/xorg/modules/drivers//intel_drv.so(i830_ddc_get_modes+0x2c) [0xb79f26ac] 4: /home/vedran/src/X/xorg/lib/xorg/modules/drivers//intel_drv.so(i830_lvds_init+0xef) [0xb79ee7ef] 5: /home/vedran/src/X/xorg/lib/xorg/modules/drivers//intel_drv.so [0xb79e9375] 6: src/X/xorg/bin/Xorg(InitOutput+0x9f9) [0x80a74d9] 7: src/X/xorg/bin/Xorg(main+0x26b) [0x8070deb] 8: /lib/i686/cmov/libc.so.6(__libc_start_main+0xe0) [0xb7b63450] 9: src/X/xorg/bin/Xorg(FontFileCompleteXLFD+0x1f1) [0x8070441] I'm building with -g (debug symbols, but the backtrace doesn't contain the line numbers and .c file names for some reason). Complete log and xorg.conf file attached. DRM modules are also latest git.
