First of all, excuse my English.
I have a problem with a configuration and can't find the solution, so … looking for help with it.
This is a PC that is only used as a multimedia center (netflix, surfing the web, etc.)
The PC is connected to an amplifier (Denon AVR-4306) that changes the sound and image of various equipment (wii, xbox, tv deco and pc), and sends both signals through a single HDMI to the television (Panasonic TH- 50PX70E).
PC ---> amplifier(Denon AVR-4306) --> Tv(Panasonic TH-50PX70E)
Ubuntu detects the wrong monitor and consequently the image size is wrong and out of bounds (this is a physical size issue, not a resolution or DPI issue).
I searched and Googled similar problems, but I didn't find any answers, most of the similar questions are geared to change the DPI, which is not my problem.
Ubuntu mistakenly detects the Denon amplifier as a 65-inch Denon TV and displays a size that does not fit on my TV (too large, part of the image is lost in each margin, so I can barely see the menu bar in the margin left or the system bar in the upper margin).
I remember that before migrating to wayland, Ubuntu allowed to scale the image just like Windows, but with the change to wayland that feature is lost.
Some relevant information from the PC:
OS: Ubuntu 19.10 (GNU / Linux 5.3.0-24-generic x86_64)
CPU: Intel (R) Core (TM) i3-4330T CPU at 3.00GHz
GPU: Intel Xeon E3-1200 v3 / 4th Gen Core Processor Integrated Graphics Controller
What I tried:
XRANDR: I tried to play with xrandr to no avail,
xrandr –fbmm 1106×622
This does nothing, I tried some other xrandr commands and they are also ignored, after reading it seems xrandr doesn't work with wayland.
I edited the xorg.conf file to add the specifications of my TV as follows:
Driver "vesa" #Elija el controlador que se utilice para este monitor
Identifier "Panasonic_TH-50PX70E" #Contraiga la sección Monitor+Device a Screen
DefaultDepth 24 #Cambie la profundidad (16||24)
Modes "640x400_70.00" #Elija la resolución
DisplaySize 1106 622 # En milímetros
Look for each copy of xorg.conf in my installation and add the mentioned settings to all of them, these are the locations of the files:
This doesn't work either …
Any suggestion will be welcome, at this time I have dual boot with Windows because Linux is not functional but I would rather have this as a Linux machine.
I've always been with gnome but if kde has this feature I wouldn't mind changing.
Thanks in advance for any assistance.
