I am running Linux on the Lenovo X201, Intel graphics card [0]. Earlier kernel versions (around 2.6.35, iirc) sometimes allowed me to restore it by switching away from X to the console, which stopped working broken display (weired characters everywhere) after some time. With 2.6.37-rc7 this does not work. After about 4-5 suspends the screen stays black, the machine is still working otherwise (i.e. rebooting it works fine). It seems there's a long ongoing problem restoring the display, seeing it in various forms (including freeze) in at least * 2.6.27-rc1-00156-g94ad374, * 2.6.28-next-20090107-ikn * 2.6.28-ikn-06859-gede6f5a * 2.6.28-rc9-wl-ikn-24949-ge98df74 * 2.6.29-rc4-58-g4c098bc, * 2.6.29-rc5-ikn-00168-gba95fd4 * 2.6.30-rc7 * 2.6.31-r2 * many many more, see messages from me to LKML With some working version (just brighness related): * 2.6.29-rc7-wl-ikn-32831-g98c5597 * 2.6.30-rc3-next-20090428-04067-g72f1b63 I'm wondering whether there=20 a) is one bug coming up again and not really fixed b) are many bugs, just parts fixed c) new bugs are introduced quite often In any case, I downgraded to 2.6.36-ARCH, which works fine related to brightness and suspend/resume.
