[Solved] Cannot change display resolution in Display dialog


Just tried the "post-release update" version and so far so good.

I think part of the problem may be the quality of the screen. This square 19 inch screen was bought for my wife who requested that size. It's a Samsung SyncMaster SA450 recently bought new on special offer for $90. My own screen is a 24" ilyama Prolite XB2472HD at 4 times the price. I can run that at 1440x900. Of course, there may be other issues like font quality and driver quality. When I bought the ilyama I read lots of articles saying wide screen were optimised for video and were often poor on graphics and text. The ilyama was stated as an exception.


You're welcome and happy it worked. My laptop has a resolution of 1920x1200, so I know what it's like to stuggle with small text.  :)

Hi Scott

It says "No proprietary drivers are in use on this system" and then lists 3 driver options all for ATI/AMD proprietary FGLRX ([normal], experimental beta, post-release updates)

According to AMD my A4-5300 APU has an AMD Radeon HD7480D R7 graphics.

I decided to activate the [normal] one to start. Driver was downloaded and installed.

Restarted and I can now choose a lower resolution.

Many thanks Scot:)

Hi Alan. Does (menu>settings>) install drivers list any video driver options?


I'm struggling with the small text on my screen but cannot change the screen resolution.

When I go to Menu \ Settings \ Display then on the Display dialog there is Default set at 1280x1024, refresh rate 0.0 Hz, rotation: Normal and reflection: none. But on the all the drop down menus there are no other choices for any of these. Also there is no button to add another profile.

xrandr shows

xrandr: Failed to get size of gamma for output default
Screen 0: minimum 1280 x 1024, current 1280 x 1024, maximum 1280 x 1024
default connected 1280x1024+0+0 0mm x 0mm
   1280x1024       0.0*

xrandr --size 1024x768
Size 1024x768 not found in available modes

Suggestions please.

PS At the moment I'm using a standard square screen but once I'm fully running on Linux then i'll be using my landscape screen. This square screen is using a vga cable as I don't have a spare DVI cable.
