[8086:2a02] Live-CD intel_extreme graphics driver no longer recognizes i965GM

[joergn_1]

The latest nightlies gives a blank screen on my notebook HP6910p. I bother to find out when the changes took place in the hrevs no longer supporting my notebook graphic card: The last working one with the correct resolution of 1280x800 was hrev50483, starting with hrev50533 i got a blank screen by booting with the live-CD. As of the time i tested the latest hrev70796 with the same result.

I've made txt files for the output of listdev, listimage and a copy of the syslog of all three tested hrevs: 50483 latest working, 50533 something must have changed, 50796 latest nightly as of the time of my tests.

6 txt files of different hrevs with listimage, listdev and a copy of syslog

intel_extreme changes in that range: ​http://cgit.haiku-os.org/haiku/commit/?id=c2775a3bbe37d7e758fc73e844e5b4d499202ae8, ​http://cgit.haiku-os.org/haiku/commit/?id=bb4190f0508392ca43d912b059a10e83268ed483, hrev50512, hrev50515.

Adding PulkoMandy to CC as he made those changes.

Please retest after hrev53040.

Does anyone have this hardware to test on a recent hrev?

I might have access to a 2510p, will check.

Note to self: found two 2510p but no HP charger. Buy HP charger.

Bith new syslogs you included are apparently with the intel accelerant disabled: the driver finds the device, but then is never requested to initialize it. To debug this we need a syslog with the accelerant actually trying to drive the video card.

hrev50657, gcc2h - indeed doesn't work, display all garbled.

hrev53541, gcc2h - works fine.

I suggest we close this one as fixed.

Thanks for testing!
