#3397 closed bug (fixed)

Screen: cannot set screen modes anymore

Reported by: rossi Owned by: axeld
Priority: normal Milestone: R1
Component: Drivers/Graphics/intel_extreme Version: R1/pre-alpha1
Keywords: Cc: umccullough@…
Blocked By: Blocking:
Platform: All


The Screen preferences do not work anymore for me. I cannot set a screen mode anymore, independent of the resolution I chooose. I always get the error message "The screen mode could not be set: Invalid Argument".

This happens if I use the native intel_extreme driver.

In VESA mode I can still change screen resolutions, however VESA mode doesn't offer the 1920x1200/32bit/60Hz mode ;-(

This used to work before (at least for sure until hrev29060).

The error is exposed on hrev29107.

Addition: just tried some more, apperently only the 32bit resolution doesn't work, if I go down to 16bit, it works. However before I could happily use 32bit depth resolutions, including 1920x1200 ...

Sounds similar to #2995, #2188.

comment:3 by rossi, 13 years ago

Sounds similar, I checked them before, but the actual error message is differently and since this used to work until recently, I believe its a different isssue, even though they might of course be related.

Is that by any chance with gcc4 Haiku? mmlr was noticing the same problem, but for him it only happens with a gcc4 build, on gcc2 haiku it still worked fine for him.

comment:5 by rossi, 13 years ago

Nope, it is to be exact a hybrid build, with gcc2 being the base system and gcc4 libs installed.

comment:6 by mmlr, 13 years ago

Interesting, if it was really introduced so recently it's possible that I don't see it because I'm lagging behind. Running on a hrev28971 base here with updated individual components.

If that's the case, then my guess would definitely be hrev29060.

comment:8 by anevilyak, 13 years ago

And if hrev29060 does indeed turn out to be the culprit, the following may be helpful to Axel in tracking it down:

"And if that does not help, can you please enable debug output in the Intel GART driver (at src/add-ons/kernel/busses/agp_gart/intel.cpp)?"

Actually, my G33-based system has this problem as well - but with one difference - it didn't work before the recent change either.

It did *appear* to work (it would tell me it was in 32bit mode when i looked at the preferences), but when I tried to change screen resolutions (smaller or larger) it would fail with "Invalid Argument" until i set it to 16bit first.

I guess that's just the same bug that has recently been mentioned on the list (that the app_server does not correctly fall back if allocating memory fails).

hrev29060 should have no influence whatsoever on the i945 - the code specifically asks for the 9xx family and behaves exactly as before for those. I would just assume that you didn't notice the bug before for some reason. But in order to prove you wrong, can you please attach at least the syslog, as otherwise one can only guess.

I'm using a lower resolution (1680x1050x32), but that does not reproduce the problem.

Syslog attached.

I don't know what changed, but I forgot this bug and just used screen preferences to set this resolution after a week of working on the built-in laptop display and it works again. therefore I cannot say, which revision fixed this bug, but it seems fixed latest in 30935 ;-)

Should be closed as fixed.

comment:14 by stippi, 12 years ago

This may still be a problem, depending on some factors which have not yet revealed themselves... :-)

comment:15 by rossi, 12 years ago

Should those some factors reveal themselves, I'll give those factors the honor of loud crying in another comment to this ticket ;-)

comment:16 by scottmc, 12 years ago

Sounds like this one can be closed then?

Yep, closing.
