|
|
Hello everybody!
I've been using LXQt Desktop for a few months now and this problem has recently appeared: the monitor switches to the maximum resolution after resuming from a shutdown, but I want it not to use this resolution but a lower one...
In my xorg.conf.d folder I have:
Code: | cat /etc/X11/xorg.conf.d/15monitor.conf
Section "Monitor"
Identifier "Monitor0"
VendorName "Unknown"
ModelName "DELL P2415Q"
HorizSync 31.0 - 140.0
VertRefresh 29.0 - 76.0
Modeline "1920x1080_60.00" 173.00 1920 2048 2248 2576 1080 1083 1088 1120 -hsync +vsync
Option "PreferredMode" "1920x1080_60.00"
Option "DPMS" "true"
Option "UseEdidDpi" "false"
Option "DPI" "96 x 96"
# Option "DPI" "192 x 192"
EndSection |
and
Code: | cat /etc/X11/xorg.conf.d/18screen.conf
Section "Screen"
Identifier "Screen0"
Device "Device0"
Monitor "Monitor0"
DefaultDepth 24
Option "Stereo" "0"
# Option "nvidiaXineramaInfoOrder" "DFP-1"
Option "metamodes" "1920x1080 +0+0 {ForceCompositionPipeline=On, ForceFullCompositionPipeline=On}"
# Option "metamodes" "3840x2160 +0+0 {ForceCompositionPipeline=On, ForceFullCompositionPipeline=On}"
Option "SLI" "off"
Option "MultiGPU" "off"
Option "BaseMosaic" "off"
SubSection "Display"
Depth 24
Modes "1920x1080_60.00"
EndSubSection
EndSection |
I also have 'lxqt-config-monitor -l' in my autostart folder...
If anyone can help me, I would appreciate it in advance!
Big hug to everyone!

Hello everybody!
Today I spent the whole day trying to solve this problem and nothing... I even followed some tips to create my own EDID, but unfortunately I didn't get good results...
The only significant change I made, other than day-to-day updates, was switching from SystemD to OpenRC...
I pass on this information to help anyone who can help me and for any other information just ask...
Thanks in advance for any help!
Big hug to everyone! |

With DisplayPort, which tends to make displays completely disappear when powered off, I've had mostly good luck with simply saving the settings via 'lxqt-config-monitor'.
I'm not sure how well it works with nvidia, and any 'xorg.conf' though, since I've been using AMD and no 'xorg.conf' for a handful of years now. _________________ Kindest of regardses. |

Hello Chiitoo!
First of all I want to thank you for your help, thank you very much!
I also tried with this process, 'lxqt-config-monitor', but it only works when the session starts, after the monitor is turned off it doesn't work, this in OpenRC, because when it had SystemD it worked, that is, the process worked in the background...
And I use DisplayPort as connection to the monitor...
Big hug and thank you again! |

I'm really not sure what it could be.
I think I used to see something similar, and I think I "fixed" it by clearing the list of saved settings in 'lxqt-config-monitor', and it started remembering them again, but that was a while ago... and I forget the details.
Perhaps I'm missing some automatic process that notices the "removal" of the display, and tries to do the good thing and revert to some defaults.
I'll see if I can do some testing sometime soon, and find anything out.
I currently have 2 DisplayPort monitors and 1 HDMI TV commected, and am able to turn any of them off without things going wild. _________________ Kindest of regardses. |

Hello Chiitoo!
Thank you again for your attention!
This was one of the first things I did, clearing the 'lxqt-config-monitor' settings, but it didn't solve the problem...
Another thing I tried was creating a 'udev' rule, but I realized that the monitor turning off and on again is not controlled by 'udev'...
If you can do some tests and help me, I would be very grateful!
Big hug and thank you very much once again! |

Hello everybody!
Since this problem was getting on my nerves, I decided to give in to it, I left my monitor at 4k resolution...
If I change my mind and decide to do more tests and find the solution, I'll post it here!
Thank you all! |
