[SOLVED] Display Video Monitor Resolution failed to resize

Postby hankivy » May 29th, '15, 06:18

My Mageia 4 system was fixed on a 1024x768 resolution. The Mageia Control Center could not change the resolution to a larger number of pixels. My system had been running with a larger number of pixels, had a power outage event, went to 1024x768, and would not change.

HOW IT LOCKED UP:
My system has a UPS. I was playing a game, "Battle for Wesnoth', in full screen mode. A local thunderstorm took power down, and up several times. Each time the power status changed another message window came up on top of the game that wanted to be on top of the monitor. Normally clicking on the power status message window would make it go away. This time it would not. :cry: I suspect the game was catching the mouse event before the power status message window could see it. I tried to quit the game before the UPS shut the system down, but the game pops up a confirmation message window before quitting. But I could not see the confirmation message window, it was likely behind the power status message windows. The power status message windows were filling the center of the screen from top to bottom. Now I started pressing and releasing the power button on the tower, several times. The system finally powered off. [The full screen mode of the game may have changed the default resolution of the monitor.]

RECOVERY OF SYSTEM:
After the electricity came back on, the system was fixed on a 1024x768 resolution. I tried the Mageia Control Center, selected "Hardware", launched "Set up the graphical server', selected 'Resolution'. The resolution was 'automatic". [I used a 1024x768 wallpaper picture to check the resolution.] The resolution button only gave me a few choices, automatic, and other. I tried some larger choices for a new resolution. But it always went back to 1024x768.

CHANGING MONITOR RESOLUTION:
I was logged in as the user hank. I switched user to root, and ran the following commands:
Code: Select all
[hank@HIvyTower ~]$ sudo su - root
[sudo] password for hank:
[root@HIvyTower ~]# env | grep -i display
[root@HIvyTower ~]# export XAUTHORITY=/home/hank/.Xauthority
[root@HIvyTower ~]# export DISPLAY=":0"
[root@HIvyTower ~]# monitor-edid -v
[root@HIvyTower ~]# xrandr --verbose
[root@HIvyTower ~]# xrandr --output HDMI1 --mode 1680x1050
The two export commands tell the utilities later which display I wanted to talk about, and gave them the authority to do so in my window. The last command changed the resolution of the monitor at that moment. Then I tried the Mageia Control Center, selected "Hardware", launched "Set up the graphical server', selected 'Resolution'. The resolution was 'automatic". I selected Other, reselected "Resolution", and found more sizes offered. I picked 1680x1050. It continues to use the 1680x1050 size after several power off shutdowns and reboots. It is all good. :D

Below are the ouputs of the "monitor-edid -v", and "xrandr --verbose" commands, and contain a lot of size options and monitor name HDMI1.

Re: [SOLVED] Display Video Monitor Resolution failed to resi

Postby doktor5000 » May 29th, '15, 22:12

Is this supposed to be a solution? Then I'd move it to the tips&tricks subforum.

Totally apart from that, you should distinguish between what you configure in drakx11 as default resolution for the X server and the monitor,
and what you configure with xrandr, which are two pretty different things. Recommendation is to leave it in MCC to plug&play and don't set a resolution,
and change it during runtime dynamically with the relevant tool of your desktop environment via xrandr.

Re: [SOLVED] Display Video Monitor Resolution failed to resi

I thought it was a solution. MCC, and drakx11 were not changing the resolution, immediately, or on the next reboot. :( Maybe I was using drakx11 wrong, or expecting it to work differently than it does. :oops: xrandr was used once and only once, in an act of desperation. After that I was able to use MCC, and drakx11 successfully. When my system reboots, and I login, the preferred resolution comes up every time, without using xrandr.

If I had confidence that I could put my system back into the same sorry state that had my monitor resolution locked up, then I would test further, to learn if xrandr had really been needed. All I can do is document one data point, one user's experience. If no one ever has this issue, or needs to use this solution, then we can all go on our merry way, and forget it ever happened. If everybody thinks this never happened to anyone else, and does not take the time to document it the best they can, then we will never understand the real scope of the issue, or document a work-around.

One possible issue, might be that my monitor did not change it's resolution during the test interval, went black during the test, I did not see an OK button to click, drakx11 went back to a known good, (but undesired) resolution before the monitor could respond to the testing of the newly selected resolution. If xrandr had used an improper resolution, and my screen was full of gibberish, then I would have cycled power on the tower. The system would have come back up with a usable, but not optimal resolution, and I would start over.

At this point, my system is working fine. :D
