Hardware: HP nc6320 with CoreDuo T2400, i945GM and a 1400x1050 LCD panel. Using the standard Linux kernel 2.6.16. Currently using VESA driver. 915resolution v0.5.2 is used to "enable" the 1400x1050 which is not listed in the VBIOS. The Xorg server 6.9.0 is running fine @1400x1050 if started by the root user. It crashes directly after startup (i think on the first drawing operation) if started by an ordinary user: Backtrace: 0: /usr/X11R6/bin/X(xf86SigHandler+0x8a) [0x8088b2a] 1: [0xffffe420] 2: /usr/X11R6/lib/modules/libfb.so(fbCopyNtoN+0x214) [0xa78c08d4] 3: /usr/X11R6/lib/modules/libfb.so(fbCopyRegion+0x1df) [0xa78c117f] 4: /usr/X11R6/lib/modules/libfb.so(fbDoCopy+0x46b) [0xa78c160b] 5: /usr/X11R6/lib/modules/libfb.so(fbCopyArea+0x78) [0xa78c16b8] 6: /usr/X11R6/lib/modules/libshadow.so [0xa78e0c34] 7: /usr/X11R6/bin/X [0x8168ea1] 8: /usr/X11R6/bin/X [0x81b2240] 9: /usr/X11R6/bin/X [0x81b06ac] 10: /usr/X11R6/bin/X [0x81679f0] 11: /usr/X11R6/bin/X [0x816b8b0] 12: /usr/X11R6/bin/X(miWindowExposures+0xd8) [0x81a2208] 13: /usr/X11R6/bin/X(miHandleValidateExposures+0x76) [0x819a936] 14: /usr/X11R6/bin/X [0x8089ef3] 15: /usr/X11R6/lib/modules/drivers/vesa_drv.so [0xa7a39c05] 16: /usr/X11R6/bin/X [0x80b7343] 17: /usr/X11R6/bin/X(xf86SwitchMode+0xba) [0x8084d1a] 18: /usr/X11R6/bin/X [0x80955f5] 19: /usr/X11R6/bin/X [0x8095821] 20: /usr/X11R6/bin/X [0x8175ee5] 21: /usr/X11R6/bin/X(Dispatch+0x171) [0x80c7e01] 22: /usr/X11R6/bin/X(main+0x3ed) [0x80d463d] 23: /lib/tls/libc.so.6(__libc_start_main+0xd4) [0xa7d8ce14] 24: /usr/X11R6/bin/X [0x806ff61] Fatal server error: Caught signal 11. Server aborting The default i810 driver (contained in the 6.9.0 slackware package) does not support the 945GM chipset, and the updated version taken from http://dri.freedesktop.org/snapshots/i810-20060403-linux.i386.tar.bz2 is crashing in the similar way (with different backtrace of course). The Xorg 6.9.0 server (VESA) is running fine @1280x1024 (which is listed in VBIOS) both as an ordinary user and as root. Xorg 6.8.2 (vesa) is working fine @1400x1050 both as an ordinary user and as root.

Sorry about the phenomenal bug spam, guys. Adding xorg-team@ to the QA contact so bugs don't get lost in future.
915resolution bugs are an anachronism. Use KMS.
