max resolution 1024x768

Hi, i have an Acer monitor 1366x768 but max resolution i can choose is 1024x768.

Code:
xrandr

Screen 0: minimum 320 x 200, current 1024 x 768, maximum 16384 x 16384
DVI-0 disconnected (normal left inverted right x axis y axis)
HDMI-0 disconnected (normal left inverted right x axis y axis)
VGA-0 connected primary 1024x768+0+0 (normal left inverted right x axis y axis) 0mm x 0mm
   1024x768      60.00* 
   800x600       60.32    56.25  
   848x480       60.00  
   640x480       59.94
What can i do? The mode 1366x768 is working fine in Windows 10.

Re: max resolution 1024x768

Code:
cvt 1366 768 60
This gives me:

Code:
 
# 1368x768 59.88 Hz (CVT) hsync: 47.79 kHz; pclk: 85.25 MHz
Modeline "1368x768_60.00"   85.25  1368 1440 1576 1784  768 771 781 798 -hsync +vsync
Code:
xrandr --newmode "1368x768_60.00"   85.25  1368 1440 1576 1784  768 771 781 798 -hsync +vsync
Code:
xrandr --addmode VGA-0 1368x768_60.00
Code:
xrandr -s 1368x768
This mode works fine but its a few mm too high and a few mm too much to the left.
And not 100% clear.

Any ideas?

I just had a similar problem (313348) and the solution was the in the built-in monitor configuration menu (totally apart from Fedora software).

Yeah, once you configure with xrandr -s ...

then go to your monitor and see if you can find an "auto configure" button, which will most probably do the job and adjust the clock and positioning appropriately.

Yes i have already done that.
After that i update one package, linux-firmware and now it is working.
The position is good but i still have to use xrandr every time i reboot.
