Boot from SD and edit screen res on native OS?
#1
I played around with a Mangaro image on SD and all was well.  Tried changing don't size for these poor old eyes and worked.  Also found screen resolution change option.  So... I booted back up on the default internal image and tried the same.  Found both settings.  I set the screen resolution ton1024x768, as was the next visually larger size... Set to system wide and applied then rebooted.  Now, after logging in (with larger fomt on login window).... It boots to a blank screen.  No curaer, not mouse pointer.  It occasionally does a light flash, like it's trying a different resolution, but now change.  I don't have a USB to HDMI adaptor, so am stuck.

I can still boot to Mangaro, however.  can iount the internal drive, and change a config file to get back to theddefault resolution1292x1080?

Thanks in advance

you don't want to change the resolution. keep this at FHD. you can use scaling if supported by the window manager.

MATE does support HiDPI scaling. Install/open MATE Tweak. Start around x1.15 and work your way up as needed.

Very good... Thanks for the tip!  Is my process, listed above, correct to get the resolution set back tondrlefault?  As, right now .. booting from the default OS, I just have a black screen. :-( I would need to know what file to make the change in, however. I can probably being around until I find it. I've done a reasonable amount of work on Linux, but pretty much only on working systems. :-)

I am not sure about how manjaro does this... we're you using kde or xfce?

my first thought is to jump to a console and load a different window manager and see what happens... my go-tos are fluxbox and sway.

"system wide" sounds like a config file

Yes... That's what I'm looking for. . the display/monitor config file where the change I made in the default is .  I'm booting to Manjaro on SD card, then using terminal to go to the internal drive where the default OS is located.  I assume it's in it's /etc folder.  I thought I had found it, edited the Tex file, saved, then shut down and pulled the SD/Manjaro card and attempted to boot from the internal drive again.  Still no go.  I can log in, and it seems to finish booting , but don't get a desktop screen after... Just a blank screen.

I can't make any changes in the GUI when booted from Manjaro, as it will only effect Manjaro on the SD... Not the internal OS config.  So, I am booting from Manjaro to make a manual change on the default internal drive.  Does that make sense?

Per this post, you need to make your edits to the xrandr config.

Very good!  I'll look at the post tonight.  I did make a change to one of the files in that folder, and it didn't work... But I'll read the list and re-attemot.  I likely missed something!

Thanks!
