[intel_extreme] 1600x900 is not supported (regression)

[starsseed]

Booting Haiku hrev47195 the best resolution available for my 1600x900 laptop display is 1440x900.

1600x900 used to be perfectly supported with hrev44989

PCI-ID :

8086:0116 (Intel SandyBridge HD3000)

driver loaded :

/boot/system/add-ons/kernel/drivers/dev/graphics/intel_extreme /boot/system/add-ons/kernel/drivers/dev/graphics/vesa

Really, you have been around here long enough to know that this ticket will most likely just rot away in Trac unless you:

1) Attach your syslog. 2) Reduce your monster regression range by testing nightly builds until you have something workable. ​http://haiku-files.org/

[starsseed]

the regression appeared between hrev45797​ and hrev45831​

[luroh]

Thanks! Given that hrev45822 and hrev45828 are in your regression range, perhaps korli would like to have a look.

The first syslog is from a VirtualBox machine, which does not have access to the host video card.

Did you upload the wrong thing, starsseed?

[starsseed]

@waddlesplash : yes I uploaded the right log. I Install Haiku from the vmdk image to the Physical hdd (sda1) within VirtualBox so the installer copy the syslog. When I restart in the physical environment, the syslog is not cleaned up so the first part of the file contains the virtual session log, and the second part the log for the physical session (I will upload a reduced log)

And now the reelevant part : comparing grep intel_extreme syslog.r45797

I suspect that after the intel_gart support was added in hrev45822, the intel_extreme driver try to set the resolution instead of continuing to use the one set by the BIOS (note that in both cases, the boot splash screen seems to be set at 1600x900)

[waddlesplash]

I'm not so sure about that. I think the culprit is more likely hrev45828 -- hrev45822 doesn't break existing configurations, as it evaluates the same way on bridges that aren't multi-display.

[korli]

In hrev45797​ the vesa driver is used, in hrev45831, the intel_extreme driver is used. I'd suggest to blacklist the intel_extreme driver as a workaround. Please check if this works.

About the bug itself, it seems intel_extreme couldn't retrieve edid information from your panel, and/or the pll limits used aren't good enough to list the native mode. Both are reasonable reasons in my opinion.

[pulkomandy]

Moving non-fatal hardware issue out of alpha5 milestone.

[axeld]

Please try with a revision newer than or equal to hrev47304.

[axeld]

hrev47307 should also make it keep the native resolution after the boot screen (this will only work if you haven't saved it already, ie. on a new install).

[starsseed]

Fixed (hrev47313) it works fine now. Thanks
