CRT Monitor is iiyama vision master pro 451  19 inch
Screen resolution altered via menu/settings/display –  monitor identified as iiyama North America  18” no model named.   However  In previous ll2.8 32 bit  monitor identifed as iiyama 19 inch with maximum resoltion option 1024 x 768.

The only difference is that I have added extra RAM and matched  ram on each channel so achieving proper channel pairing.  This might have improved video capability??

Recent  fresh install of ll 3.2 64 bit.  So no recovery point other than default.

Confirm monitor is working still – not monitor fault  by using live DVD.

AS can’t get a screen so that I can log on, but can get live DVD working, is there a way to alter screen resolution of the LL set up on the HDD from the live DVD screen?

How did you change resolution?
- terminal or file manipulation or GUI (display)??
- How recent of a system restore??

If terminal - you can access TTY to change things back as well as use CLI for Systemback to restore...

Perhaps xrandr to the resolution you prefer if changed via GUI.. (again TTY)
Code: [Select]
xrandr -s 1024x768
To access a TTY display, press: CTRL+ALT+F1.. to go back to desktop CTRL+ALT+F7
Will need to logo in to access..

My main desktop on LL3.2 64 bit. Integrated video intel as per main profile.   Was happily running on 1024 x 768.    Opted to try higher resolution via display settings and screen went into x/y oscillations.   Did emergency shut down - holding down off button.  On rebooting, screen still in x/y oscillations totally unusable.

Any ideas please welcomed on how I can change screen resolution back to 1024 x 768  when I can not use screen.   Can it be done via grub and if so how.  Thank you
