[Solved]: X Screen Does Not "Fit" (too small) the Monitor

Postby w4kh » 2019-01-28 20:00

I was trying to scroll through virtual screens (CNTL+ALT+Fn) and was distracted, and hit some Key Combination that reduced the screen to something much smaller than the monitor size. Unfortunately, due to hand/finger size and arthritis, I have no idea what combination caused my X screen to shrink, as it could have been CNTL+, or ALT+, CNTL+ALT+, and either a function key or a keyboard character. After trying just F11 with no change and uttering a few naughty words, I went to the "Configure Desktop" by right-clicking in the Desktop background, and was able to adjust the height, but NOT the width.
The monitor is 32" and presently there is 3 1/2" of black "border" on both left and right sides of the "screen" in X...
However, when I log out, the X-login screen is full size, full height and full width of the monitor.

Since randomly poking at key combinations often results in "unintended consequences" (also unwanted consequences), I sought help from Google and these forums... I already know how to resize a window within the screen, but that is NOT the problem I am facing... Far too many Google responses conflate window and screen AND apply to Microsoft versions. Here, the majority of responses were about multiple monitors or multiple windows. Every list of Shortcut Key Combinations that I have found, going back to solutions posted 8 to 10 or more years ago, does not address viewable screen and monitor size.

Surely someone knows... I'm happier on the command line, but I need X for a variety of things, and now my desktop has shrunk and is harder to manage than it was before my fat fingers fouled it up! :?

Re: X Screen Does Not "Fit" (too small) the Monitor - Need a

Since the problem does not appear when X starts and the display manager comes up, why do you think it's an X Screen issue? Wouldn't it be some shortcut key combo in the desktop environment? Maybe a zoom, or zoom out? An accessibility feature for eyesight challenged, or maybe a shrink-to-fit thing for external projector? Since you don't mention which desktop environment, then I can't search for specifics.

Maybe try creating a new user account and use that until you figure out the hotkeys.

Re: [Solved]: X Screen Does Not "Fit" (too small) the Monito

The solution was non-trivial, only because I had tried the screen that solved it yesterday to no avail...
Solution:
SYSTEM SETTINGS ---> HARDWARE ---> DISPLAY AND MONITOR ---> DISPLAYS
"Whew!"
Once there I moved the Resolution "ball" in the center to the right until resolution was set to 1360x768@60.02
And, VOILA! The Desktop grew to the edge of the monitor, and the 3 1/2 inch side boarder is now gone!

I wish I knew what keystroke combo originally rest the desktop resolution to the smaller size, but after looking up every reference I could find for keystroke shortcuts, I could not find the combination that started the mess in the first place... I am grateful to Thomas Pfeiffer, whose blog post "Do Plasma users know all the useful shortcuts?" Posted on February 23, 2016, led me to the solution.

xrandr --output VGA-1 --mode 1360x768

^ This method is desktop agnostic. And quicker.

I only looked at enough of the man page for xrandr to do the list... Now, xrandr is part of the tool bag... Thanks again
