[opensuse-factory] Leap 42.1 - Too big display problem on a laptop
My colleague has a stubborn problem on Leap 42.1 that refuses to go away.
The problem suddenly appeared.
We have tried removing ~/.kde4 and using xrandr.
Login using Plasma5 or KDE Plasma Workspace results in the same but
IceWM gives a normal sized screen.
Help appreciated.
Regards
Sid.

Just on my way out to the Cricket Academy. See if this works http://www.perpetualpc.net/srtd_resolution.html xrandr
To change the resolution (monitor display) from the command line ( using a terminal window ) do this: ( when x is running -- don't exit Xwindows just use a terminal window. This is done from the command line. ) [ xrandr ] this command will bring up information like this:
SZ: Pixels Physical Refresh 0 1024 x 768 ( 271mm x 201mm ) 75 70 60 1 800 x 600 ( 271mm x 201mm ) 85 75 72 60 56 2 640 x 480 ( 271mm x 201mm ) 85 75 72 60 *3 832 x 624 ( 271mm x 201mm ) *74 4 720 x 400 ( 271mm x 201mm ) 85 5 640 x 400 ( 271mm x 201mm ) 85 6 640 x 350 ( 271mm x 201mm ) 85 Current rotation - normal Current reflection - none Rotations possible - normal Reflections possible - none
This will show the resolutions possible on your monitor. The star indicates what is currently being used. To change resolution use a command like this: [ xrandr -s 1024x760 ]
This will immediately change the resolution; in this case to 1024x760. ( it takes about .5 seconds on my system which uses a "Super View 1280" monitor which is actually an Hitachi cm500 as far as specifications go -- I am using RedHat with kernel 2.4.20-6 and Xfree86 version 4.3.0) To check for xrandr on your system type [ xdpyinfo ] (If you see RANDR listed under number of extensions then it should work.) Also typing [ xrandr -s ] will give this information:
usage: xrandr [options] where options are: -display <display> or -d <display> -help -o
or --orientation -q or --query -s <size>/<width>x<height> or --size <size>/<width>x<height> -r <rate> or --rate <rate> -v or --version -x (reflect in x) -y (reflect in y) --screen <screen> --verbose This assumes your (crt) monitor is set up with vertical and horizontal specifications that it can handle. Be aware that you can inadvertently destroy your monitor with the wrong settings.

Hi Sid, I've broken my Leap system and haven't a clue how or how to set about fixing it! Can you point me in the right direction, please?
What happened was I booted up my system normally, started firefox and started checking 3 or 4 sites, as I do normally. Went to the first site OK but wanted to increase the size of an image and I think I must have caught a wrong key, because the screen went to an enormous size with scroll bars on the side and bottom. When I move the cursor around, the screen scrolls. The resolution, normally 1280x800 had the appearance of VGA (640x480) and I've no idea how to reset it.
I rebooted and as it was coming up, it went through the usual terminal stuff, loading the initial RAM disk, etc and then blanked as usual, popped up the light bulb and Gecko and started the scroll bar under the gecko. When it got about half way along, it suddenly expanded the screen again, the light bulb was taller than the screen and the scroll bar completed. The screen was then the massive size, the KDEWallet prompt showed up, I was able to enter the wallet password and got to my home screen.
Again, the screen on both desktops was enormous and the icons on the launcher and task bar seemed like VGA resolution - or maybe just big. I had a look around but couldn't find anywhere to reset the screen resolution. it's almost as if the screen size is 1280x800 but with VGA size pixels. assume I must have triggered this effect myself accidentally but haven't a clue how.
I tried another disk I have lying around with a Windows system on it to check if it was hardware but not so, it came up normally. Put the Leap disk back in and it came back up with the huge screen. When it shuts down when it gets to the console screen just before it closes, that is back to normal. When I started a terminal session from the big screen size, it to was way bigger than the display.
How can I fix this please? is it a parameter file somewhere or do I need to reload KDE (preferably non destructively) or something else?
Thanks and best regards, Sav.

Maybe this is related to the zoom functionality https://forum.kde.org/viewtopic.php?f=111&t=117741 Check ~/.config/kwinrc for the entry [Effect-Zoom] InitialZoom=1 and if the value is !=1 set it to 1. as a post there suggests: "Then i pressed shift+alt+F12 two times in order to disable/enable the desktop effects."

Thanks Dieter, I'll get him to check the setting. I don't have the entry in my kwinrc but the URL may explain what happened as he suspected it was something he did. Regards Sid. -- Sid Boyce ...

Hi Sid, I think I fixed it! As you know, nothing I seemed to do was having any effect, so next random thought was "If it thinks it wants a big screen, I'll give it one!" My Raspberry Pi screen has a DVI port and an HDMI to DVI cable (the Pi, as you know, uses an HDMI output). Plugged the screen in and toggled the switch screen key. The display switched to the external screen at more or less the right shape (the external screen is full HD (1920x1080). Toggled the switch again, both screens blanked. One more toggle, and it switched to the laptop screen at the right proportions and the right size! And this survives over a reboot. -- Sid Boyce ...
