Description (last modified by bga)

My desktop computer is connected to a Samsung Syncmaster 22" monitor with a native resolution of 1680x1050. As I am using the VESA driver ad my video card BIOS does not seem to export widescreen modes, I was using 1400x1050 as my resolution.

I just updated haiku to hrev32034 and, now, I can only set 1280x1024 as the maximum resolution.

Interesting enough, going to the boot menu and selecting a video mode to use does show 1400x1050 but selecting it has no effect (it ends up in 1280x1024 after boot).

I'm in a similar situation, except that my graphics were native before but are now vesa.

I have a widescreen monitor capable of 1920x1200 (16:10) with a supported ATI card (which likewise does not export any widescreen modes) which can drive the monitor at full resolution in Linux but does not in Haiku. (Never worked.) Instead Haiku falls back to vesa in recent revisions. (No refresh rate option in Screen. Vesa accelerant in use. Max resolution 1600x1200 IIRC.) And thus loosing a few resolution options, in Screen.

First of all, I would think that those are totally unrelated problems.

Then, pinpointing to the release where this happened would help tremendously helpful, as would be syslogs. There have been no changes that I know of that could produce either problem.

Culprit is hrev32020. Reverting it got my 1400x1050 mode back.

I must have been mistaken about having native support for my graphics card, and using Vesa all along. (My card, RV710, Radeon HD 4350, appears to be unsupported by the radeon driver.)

I've attached my syslog, and wonder what the "Additional Video Mode" is. Is that just the monitor's stated preferred resolution, or an actual mode that could be used?

Your card is definitely not supported natively. In fact, it is in the same family as mine (which are two HD 3870).
