Making Tweak display resolution permanent [Solved]

[M270]

MX-23.5 64bit, Xfce
My laptops native screen resolution is 1920x1200, which makes difficult to use, especially with some of my legacy programs. I reset the display with MX Tweak to 1280x800 which works well, but even after saving the selection, on reboot it reverts to the higher resolution. I have reviewed and tried the solutions on related posts, but nothing seems to work.
Thanks for the help.

If using Display doesnt resolve it, then as workaround until a true fix is found... you could try to create a script to set the resolution using xrandr at logon.

Code: Select all

xrandr -s 1280x800

[dolphin_oracle]

its possible mx-tweak's resolution setting doesn't work with Xfce's latest 4.20. I will investigate that. Please use the Xfce's Display utility directly.

With the changes to Xfce's dislay utility, I'm thinking the MX-Tweak display tab is mostly moot at this point.

[Jerry3904]

Seems like it.

[M270]

Using the Xfce display manager and scaling the native 1920x1200 by 1.5 gave 1280x800. The change persisted on reboot so I am a happy camper.
Cheers

[dolphin_oracle]

the funny thing is tweak uses xfce's xfconf values to store the information. maybe a setting item has changed

[dolphin_oracle]

hmmm

as long as your display designation doens't change (IE, the system dedects a new display), mine is holding ok. the resolution and scale settings appear to be the same.

but there are certainly plenty of oddities in xfce/xfconf at the moment.

[Fritx]

I'm having the same problem with a TP x390. The Xfce display manager doesn't work at all. At some point, the value was permanently adopted via MX Tweak. Something isn't working properly.

[dolphin_oracle]

mx-tweak and the Xfce Display utility use the exact same settings.
