Some resolutions in VESA no longer work

[j_freeman]

Some resolutions--such as 1440x900 and 1920x1200--can be selected, but after rebooting the resolution is 800x600. The Screen preflet acts as if whatever was chosen is the current resolution, but of course it isn't.

I don't know the exact revision that stopped working correctly, but it was recent (last 2 weeks or so).

Tested under r24560 in VMware Workstation on Windows XP.

I see the same problem on real hardware here. Stuck in 800x600 but prefs app says whatever I pick. Tried with r24581 here.

Should be fixed with r24675. Please retest.

[j_freeman]

Tested in r24688. 1440x900 and 1920x1200 are no longer even listed as available resolutions.

That is because your VESA BIOS does not list them as available modes. The VESA driver can only support the modes listed in your graphics board's BIOS. Ie, it was incorrect before, that the modes got listed, and the code is correct now to not list modes which can not be supported. Please note that your graphics board would probably support these modes if a native driver for your board would be available. Only, the VESA driver can not configure your board for display modes, only through it's VESA BIOS. So everything seems to be working fine now as far as what is possible with VESA.

Ah, I see. In that case, I suppose the ticket can be closed.

Off topic: Is there any way to force a certain mode, one that isn't listed? I ask because it was nice having native fullscreen at 1440x900. ;)

Wait... you have been using the VESA driver at 1440x900 before, and now this does not work anymore? Because that would be a bug then.

Correct. Up until recently, 1440x900 was listed and worked fine.

Replying to j_freeman:

Correct. Up until recently, 1440x900 was listed and worked fine.

Are you sure you haven't changed your hardware that does it? Some adapters publish resolutions like that, some (most) don't. If you are sure your hardware hasn't changed (also no BIOS upgrade in that time), it would be very nice to know what change may have triggered that. Can you try out older revisions?

[j_freeman]

I'm positive I was able to use the resolution with the VESA driver, but I can't seem to reproduce it. Yesterday I went as far back as a month in testing older revisions, but they either didn't list the resolution or listed it and it displayed as 800x600.

I did upgrade my version of VMware Workstation recently, and that could have very well upgraded the VMware BIOS. That's the only thing I can think of. I'll try and go back to an older version of VMware when I have some time and see what that does.

[axeld]

That would perfectly explain the situation. I'll therefore close this ticket for now.
