I am having the same issue. I'm using packages from Tormod's PPA - Intel driver (v2.5.99.1) - wserver-xorg-core 1.5.3+git20081216
My system runs Kwin with desktop effects enabled. I have no external mouse nor usb keyboard, it's all built in the laptop. I happens randomly, sometimes while I'm using the computer or some other times while the computer is idle. The system does not completely hang when it happens, I can remote connect by SSH, kill Xorg and it's back to normal (until the next lockup) Here is the backtrace : Backtrace: 0: /usr/bin/X(xorg_backtrace+0x3b) [0x813164b] 1: /usr/bin/X(mieqEnqueue+0x237) [0x8110ba7] 2: /usr/bin/X(xf86PostKeyboardEvent+0xa7) [0x80d18d7] 3: /usr/lib/xorg/modules/input//evdev_drv.so [0xa74d00e9] 4: /usr/bin/X [0x80cce47] 5: /usr/bin/X [0x80b45dc] 6: [0xb7fb7400] 7: /usr/local/lib/libdrm.so.2(drmWaitVBlank+0x28) [0xb7a73928] 8: /usr/lib/dri/i965_dri.so [0xa74fe05d] 9: /usr/lib/dri/i965_dri.so(driWaitForVBlank+0xfb) [0xa74fe2eb] 10: /usr/lib/dri/i965_dri.so(intelSwapBuffers+0xc7) [0xa7508647] 11: /usr/lib/dri/i965_dri.so [0xa74ff607] 12: /usr/lib/xorg/modules/extensions//libglx.so [0xb7ad8b74] 13: /usr/lib/xorg/modules/extensions//libglx.so [0xb7acb2ce] 14: /usr/lib/xorg/modules/extensions//libglx.so [0xb7acec0a] 15: /usr/bin/X(Dispatch+0x34f) [0x808c8ef] 16: /usr/bin/X(main+0x47d) [0x8071d6d] 17: /lib/tls/i686/cmov/libc.so.6(__libc_start_main+0xe5) [0xb7bb0685] 18: /usr/bin/X [0x8071151] ERROR: Server Lockup!
