Is there some other reference with more cmdline options for starting installation? KMS obeys valid video= on cmdline, but X ignores it.

I would be interested too. I cannot use KMS drivers in QEMU because it insists on using window twice the size of physical notebook screen (and without any scrolling possibilities, but even with scrolling it would be too awkward).

video= seems to be observed by kernel but not by X in installer. Using nomodeset works and lets me select correct resolution.

Does 800x600 exist? 768 already exceeds usable screen size (my screen is 1200x800 - subtract panel and windows decorations ...)

No, check Documentation/EDID/HOWTO.txt in the linux kernel sources.

Can I use manually generated EDID during installation?

I'm not aware of an obvious and easy solution but I'm quite sure with some dirty hacks you could get it to work. But then the faster way would be to just use text mode.

Video= does the job well enough for the ttys. Why doesn't it work for Xorg?

Good question. I'd expect X to keep whatever mode setting was in effect unless explicitly told otherwise. -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org

Good question. I'd expect X to keep whatever mode setting was in effect unless explicitly told otherwise.

The Xorg's kms modesettings driver will pick preferred mode (usually the native resolution) and set to it unless you explicitly override with monitor or screen sections in /etc/X11/xorg.conf.d/.

So how does one accomplish that in an installation setting, which is what $SUBJECT is really about? The subject URL does not present any information on how one might get the installer to use a mode other than that specified as EDID preferred.

I didn't know there's any other measures offered by X for setting other modes.

For most quirks that need to be dealt with at installation time there are cmdline parameters that can be used as workarounds. The question isn't so much whether X could be told to apply a cmdline option for X to use as it is why it doesn't seem to have such already. If framebuffer can obey video=, why can't X? Until and unless it happens that X normally accepts a cmdline gfx mode option that applies to X, there needs to be a cmdline workaround to get whatever configuration mechanism the installer uses for X to translate the video= option to whatever X requires to get it to use that mode for installation. Nomodeset is a lousy alternative, as it gets applied to the installed system's cmdline configuration by default, and uses the vga= options, which are anything but intuitive to select appropriately, and only offer 4:3 modes regardless of actual screen aspect ratio. All the above is moot of course if there is a solution and it's just hiding from those who would use it. -- "The wise are known for their understanding, and pleasant words are persuasive."

Yes, that worked combined with video=1024x768. Which means that this is in the end effect bug in installer. Suggested F3 menu to select resolution simply does not work for any system where KMS is used. So we have yet another way to set video resolution. And it also may require building additional file and including it in kernel or initrd.
