Intel graphics randomly boots with black screen
|Reported by:||edglex||Owned by:||nobody|
This is hrev 47865 on a thinkpad x230 with intel HD 4000 graphics.
Two thirds or three quarters of the time this machine has a black screen on boot (with the intel driver). The rest of the time it boots normally and has the correct resolution etc.
The attached syslog is from 2 boots - the first exhibited the problem while the second was a successful boot.
More info: Changing display settings once booted can also cause the same issue (screen goes black to change modes and the image doesn't come back). This is mostly a problem with software that changes the screen mode itself (like SDL apps), since they change without a "return to previous settings" timeout. Actually, SDL apps seem to change the mode to the same as it already is for some reason, but I know the mode has changed because of the flash to a black screen and then back again, and afterwards switching desktops will cause the screen to turn briefly black then come back, unless I use screen preferences and apply to all desktops.
