Hi Bruno,
I'm using the last driver which is 367.27 not 21 (did you make a mistake?) see nvidia-smi attached ouput
Yes, your are right, my typo.
xdpyinfo report the 225dpi I'm expecting on my hidpi screen screen #0: dimensions: 3840x2160 pixels (433x244 millimeters) resolution: 225x225 dots per inch
For me: dimensions: 3840x1080 pixels (682x191 millimeters) resolution: 143x144 dots per inch This is the overall resolution if I have a second (Samsung) display connected. Each one of them has a resolution of 1920x1080.
Dell Precision Laptop 7510 on which I completely disable optimus I'm using only the nvidia gpu which is a Quadro M2000M
in /etc/X11/xorg.conf.d/50-device.conf I'm using those parameters Section "Device" Identifier "nvidia" Driver "nvidia" Option "NoLogo" "True" Option "AllowEmptyInitialConfiguration" "true" Option "UseEdidDpi" "False" Option "DPI" "225x225" #(75x3) # Option "ConstantDPI" "FALSE" Option "TwinView" "true" Option "TwinViewOrientation" "DFP-5:nvidia-auto-select SamePositionAs DFP-4:nvidia-auto-select" EndSection
and in 50-monitors.conf I use those ## as seen by Nvidia Section "Monitor" Identifier "DP-4" ## Dell Internal M7510 LCD DisplaySize 580 326 Option "CustomEDID" "GPU-0.DP-4:/usr/local/share/edid/ dell_m47510_lcd_edid.txt" Option "DPMS" "On" EndSection Section "Monitor" Identifier "DP-5" ## Dell P2515-Q on graphics nvidia DisplaySize 580 326 Option "CustomEDID" "GPU-0.DP-5:/usr/local/share/edid/dell_p2715q_edid.txt" Option "DPMS" "On" EndSection
I've previously exported the edid with nvidia tools for both of them.
I've those parameters since March, and didn't see any changes actually with last TW snapshots, and last Nvidia drivers.
Thanks for these hints. It made me curious, I'll try something similar also here. I have always done it in the way to have a minimal xorg.conf and let the driver decide by its own. This time I tried also a configuration with Randr: Section "Module" Load "modesetting" EndSection Section "Device" Identifier "nvidia" Driver "nvidia" BusID "PCI:1:0:0" Option "AllowEmptyInitialConfiguration" EndSection not more and not less, but using this simple configuration I get just "Randr disabled" in Xorg.0.log. I'm not sure how to handle this, somewhere there must be called xrandr with some parameters, have you customized your ~/.xinitrc? Nevertheless, I'm not absolutely sure whether this is a clean driver issue, because of the correct rendering in Gnome 3.20, a of X applications for example.
Plasma stability is related to still non working qt in TW (we need 5.6.2 to get things better, especially multi monitor with differents resolutions)
I will check this again without any overrides in settings as soon as Qt 5.6.2 arrives.
So my rough guess would be a change more in the intel gpu part of newer kernel aftecting optimus ?
I'm booting with the latest legacy BIOS, not in UEFI mode. Regarding Optimus: I tried Bumblebee some time ago, but it failed due to some missing entries from ACPI. After some analyze of the developers of Bumblebee (we compared the ACPI tables provided by my legacy BIOS mode with the same hardware running in Windows with UEFI) we found that the correct tables for Optimus are provided just in UEFI mode. A longer time ago I checked also UEFI but I was faced with other trouble although the OS was booting. I will retry it in some spare time, because I have already a newer HP BIOS version installed. In the BIOS, I have just one setting: Hybrid Graphics: Enabled/Disabled/Auto - I found that Auto is the only way which has been working with my driver installation. Really many variants, I've still not found the "golden way" among them.
Check also the nvidia version you're using which should be 367.27
It is, see above. Was a typo.
Did you try to run Plasma but using gdm ? - If working then it's more an sddm problem, but still seems strange.
While writing this still not. But I booted also from sddm to Gnome, and Gnome is running out of the box woth the correct rendering. Will check this later, if there will be any change I'll tell.
You can also have a try to use autologin and check if then plasma is run right.
Sometimes, when I'm tired about KScreen doing everything wrong I'm cleaning all files I could find in ~/.local/share/kscreen/ ;-)
