is there any way to enable more verbose logging for drivers? I have a issue with my igp (Intel HD Graphics P530) which uses the intel_extreme driver and in general works absolutely brilliant, but is blanking the display every now so often. Before opening a ticket for it, i would like to do my homework and gather as much information as possible to provide it in the ticket.
Usually this requires recompiling the driver and enabling TRACE macros (there will be a commented out
#define TRACE or similar in the sourcefiles).
Have you tried disabling screen blanking/powersaving in the screensaver preferences? It’s the main thing that could lead to a blank display (and failing to come back from it).
Hi PulkoMandy, thanks for the hint will try to rebuild the driver from sources. Disabling power management / screen blanking, made no difference. The issue occurs during normal operation and it’s duration is below a second, it’s just like the display looses sync for a very short amount of time.
