Title: dCorePlus64-stretch and vesafb video?
Post by: PDP-8 on April 05, 2018, 06:18:56 AM: Just wondering why this boot parameter is not a default for xfbdev 64-bit versions when I boot the standard iso:

Code: [Select]
video=vesafb:ywrap,mtrr:3
Without it, dragging terminals around and whatnot are sluggish and kind of jumpy on the computers I try it on unless I provide that parameter manually at the boot prompt.

To be fair, I see this same kind of issue in Corepure64 default iso's as well, but wonder what the technical reason for not using this parameter is.

Surely, if I do an actual install I can edit in that parameter to the boot stanza. Just kind of wondering why it isn't used in the default iso's to begin with.

Does this boot parameter help you with running dCorePlus-stretch64? The dCorePlus images use Xorg which was preferred by users early on in dCore, so I was curious.

Post by: PDP-8 on April 06, 2018, 06:14:31 AM: That parameter helps me greatly with either Xorg or xfbdev, but I might be a special case..

Even though I use high resolution monitors, I very rarely run at anything higher than 1024x768 - and frequently use 800x600 (or anything similarly small with my raspberry Pi's).

At these small resolutions, the video delay / stuttering is very noticeable - especially so with terminals full of text. I don't do multimedia on my *core installs, but mostly shell stuff, so I don't need full resolution anyway.

Also part of the reason for the small resolutions is that I really dig the whole flwm/fltk thing. I have to run a small resolution to make them comfortably large enough for me to use. I like all the utilities..

You might be able to see what I'm doing - boot with vga=ask, and run with say 800x600 on your monitor. Pull up aterm, xterm, fill it with text like dmesg, top etc.

Now drag it around, or do a resize with CTRL-ALT-M. Now perform the same test with the video=vesafb:ywrap,mtrr:3 option. At large native resolutions you may not notice anything. But at my fltk/flwm-lovin' resolutions, its a bit distracting.

None of this is a show-stopper for me. Just stuff I noticed. :)

But don't do it just on my account - whatever is best for the community is what matters, so don't let me stifle progress if that's the case...

Post by: Jason W on April 07, 2018, 10:18:02 AM: Since dCorePlus does not have the graphics related kernel modules and uses smaller resolution as a result, the boot parameter mades sense.
