Two installs have display resolution problems two don't

[jmarkus]

These left me with a black screen. I will sort the TV box out later.

You can ignore that message.

Code: Select all

echo -e 'nouveau\n\nloop' | sudo tee /etc/modules

Code: Select all

sudo tee /etc/X11/xorg.conf.d/20-nouveau.conf <<!
Section "Device"
    Identifier "Device0"
    Driver     "nouveau"
EndSection
!

(It's normal that the terminal warns you about security, just click "paste" and press enter)

Reboot.

You can just delete the /etc/X11/xorg.conf.d/20-nouveau.conf

Either using a live session and the file manager

or first Ctrl+Alt+F1 and then login manually, then

Code: Select all

sudo rm /etc/X11/xorg.conf.d/20-nouveau.conf

Code: Select all

sudo reboot

:not found" - still black. I can get to the command line. How can I re-install the safe video driver?

Press E on Grub, add nomodeset after quiet splash etc.. press F10 to go on boot.

If it's ok with that, make it permanent: add into "Kernel Parameters" box in "MX Boot Options".

However there's something wrong: It doesn't want Nouveau ...

btw,Thanks for the all the help Mr Finn.

I tried the nomodeset, but it does not work. Then went immediate to the command line, and line above is saying "Plymouth failed". I thought to just wipe that partition and put a clean install on the drive - problem is it doesn't see the Ubuntu Studio install on the same drive (which works fine).

I really am impressed with the seemly small memory/resource footprint of MX. I really makes old hardware feel snappy again. I have another idea, but I am waiting on an old processor to arrive in the mail to try it. Today I put the 32 bit mx 21.3 on a Shuttle XS35V4 a very low power (15watt) quad core computer the size of a paperback book. Runs great!

So, you tried this and it worked?

Or, does it now load Nouveau no matter you tried that or not?

And you installed Grub (which's checked by default) ?

At least nothing to lose to update grub once manually: sudo update-grub

No it did not work. The TV install on the Shuttle SG31G2 is still broken.

Are there command lines to fix and repair dependencies, broken packages, or to install graphics drivers from the command line/terminal?

At one point I did a search for available nvidia drivers through though the command line. It returned 9 or 10 items. Some were source, some were driver version 340, some had mx21 in their name, and one was driver v390 that the name said it was debian bullseye stable. Earlier I tried the invidia install tool when I could boot to a low resolution GUI - the only option was driver v340. Which I had to undo as the computer became unbootable graphically.

So, you tried this and it worked?

Closing the book on this one. I tried everything I possibly could to get mx 21.3 32bit working using a Sony 55" TV as the monitor and it refuses to work. Same hardware through Ubuntu Studio v20.04.2 does work - so that is the OS I will use with my music. I tried the nvidia v340 driver again, and v390 plus went back to the nouveau drivers multiple times. I honestly think the TV is the issue. It is suppose to have some kind of ai that optimizes settings, and the type of hdmi settings were changed by the TV multiple times. Thank you everyone for the help.
