Xrandr shows incorrect DisplaySize for external monitor

teffysam · 2021-01-06 13:52:11

UPDATE: Problem "may" be isolated to Alacritty. Editing ~/.config/zoomus.conf with autoScale=false fixed my Zoom client's weird dpi issue. I will address this issue within Alacritty forums and send a final update here if I manage to find a solution. Forgive me for raising a possible non-issue in the Kernel & Hardware section but I think leaving it here may be useful for others going through the same train of thought that I did... Cheers!

I only noticed this issue after I installed Alacritty and moved the terminal window to the other external monitor. The font dpi increased when I did that, at first I thought it was an Alacritty issue but it also appears to be the case with Zoom Video Conferencing client. No other apps I know of have this issue. I am using DWM as my window manager. Any help would be greatly appreciated. Of course, this is a non-issue when I used Plasma or Gnome. Perhaps the issue is with DWM... but I cannot say for certain.

           OpenGL: renderer: Mesa Intel HD Graphics 520 (SKL GT2) v: 4.6 Mesa 20.3.2 direct render: Yes

As shown above, HDMI2 is incorrectly set as 160x90mm when in reality it is 535x300mm, so I set this in:

~$ more /etc/X11/xorg.conf.d/41-monitor.conf
Section "Monitor"
    Identifier  "eDP1"
    DisplaySize	 340 190
EndSection
~$ more /etc/X11/xorg.conf.d/42-monitor.conf
Section "Monitor"
    Identifier  "HDMI2"
    DisplaySize	 535 300
    Option "RightOf" "eDP1"
EndSection

If I just mirror the monitors and remove the section with Option "RightOf" "eDP1" the dpi problem does not persist
Using Xrandr on the command line doesn't make a difference either

~$ xrandr --output "HDMI2" --fbmm 535x300

Edit:

To clarify, this is an Asus laptop connected to a Samsung Syncmaster P2470 vai HDMI. I have not installed the Nvidia drivers and only use Intel graphics.

Looks like an optimus setup and the HDMI is likely wired to the nvidia chip?
Please elaborate on the configuration and post your xorg log as well as the complete output of "xrandr -q"
The nvidia driver supports eg. (physical DPI is ~92)

Section "Device"
	Driver	"nvidia"
	Option  "DPI"					"96x96"
	Option	"UseEdidDpi"			"False"
EndSection

The names you use for the monitors may be incorrect*, post what seth asked .

* xorg monitor names usually have dashes in them and often additonal letters
example : DisplayPort-1 , HDMI-A-0 .

Sorry should have mentioned its my laptop and I only use Intel graphics, haven't installed the Nvidia drivers. Or are you implying that the HDMI is physically connected (possibly?) to the laptop's Nvidia GPU and that this might be the cause? Anyway, I edited my intel.conf file, this didn't fix the issue though.

~$ more /etc/X11/xorg.conf.d/20-intel.conf

        Option     "AccelMethod"        	"SNA"
	Option     "TearFree"           	"true"# [<bool>]

Looks like an optimus setup and the HDMI is likely wired to the nvidia chip?
Please elaborate on the configuration and post your xorg log as well as the complete output of "xrandr -q"
The nvidia driver supports eg. (physical DPI is ~92)
Section "Device"
	Driver	"nvidia"
	Option  "DPI"					"96x96"
	Option	"UseEdidDpi"			"False"
EndSection

Do you disable the dedicated GPU in the BIOS?
Please post the requested outputs and file.

The intel or modesetting driver won't respect those options, afaics they're nvidia-only.

I had updated my post with the outputs, but I'll add it here too. To answer your question I cannot disable GPU in the BIOS, my laptop model is the Asus R558UF or Asus X556UF and it does not have option to do so unfortunately.

The xrandr -q output

The Xorg log file

The nvidia GPU is ignored in that log and it looks like HDMI2 is wired to the intel chip (lspci probably shows the nvidia chip to be a 3D device, not a VGA one? The hdmi-on-nvidia is just common, not universal)
In addition the HDMI2 output doesn't look to be configured in that log either?

Best workaround would be to skip the positioning in the config and do that w/ an xrandr call when starting the session.
It's a bit weird though…

Yes that's correct

~$ lspci | grep -i  'vga\|3d'
00:02.0 VGA compatible controller: Intel Corporation Skylake GT2 [HD Graphics 520] (rev 07)
01:00.0 3D controller: NVIDIA Corporation GM108M [GeForce 930M] (rev a2)

Okay I will try this, it's funny because before the issue persisted I was calling xrandr in my .xinitrc and wasn't using #-monitor.conf. Back then there were no issues with Zoom, where it looked normal sized on both displays...
EDIT: tried, it doesn't work either. I will think about rolling back to an older kernel version just to check and as a last option go back to using Gnome if nothing else works. Thank you so much for your time.

if [[ $(xrandr | grep HDMI2 | awk '{print $2}') == 'connected' ]]; then
  xrandr --output eDP1 --auto --left-of HDMI2
  fi
