Well i just installed QEMU and do anyone here know how to open it?

the only way i know are through the command line(from the tutorial) but i want to open the GUI

 

and also does anyone know how to recompile the boot.scr and boot.txt files on windows?

i got an error on geany and there are no arm version of notepadqq and snap version of notepad++ so ican't even open scr files

well, lets just say that i gave up on recompiling boot.cmd & scr because it crashes every time i touch those files.

 

 

btw my device are an orange pi pc2 and

 

i want to modify my boot files because i have a 1366*768 monitor that only has vga and i'm using an hdmi to vga adaptor which does not correctly detect the resolution and i'm stuck with 1024*768 and black borders on the side (i can strech it but everything will look pixelated)

EDIT:

trista@orangepipc2:~$ xrandr
Screen 0: minimum 320 x 200, current 1024 x 768, maximum 8192 x 8192
HDMI-1 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  
  1368x768_60.00 (0x2b9) 85.250MHz -HSync +VSync
        h: width  1368 start 1440 end 1576 total 1784 skew    0 clock  47.79KHz
        v: height  768 start  771 end  781 total  798           clock  59.88Hz

you can clearly see that the OS detected the resolution

1368x768_60.00

but there are no modes on 1366x768(or 1368)

i have tried the tutorial above but it shows this instead

trista@orangepipc2:~$ sudo xrandr --newmode "1368x768_60.00"   85.25  1368 1440 1576 1784  768 771 781 798 -hsync +vsync

Hi,

You can connect to your Pc2 by using putty in windows and ssh into the Pc2.

For editing try midnight commander (mc) from a terminal. Point it to the desired file and press F3 to view, F4 to edit.

If not already installed, do apt install mc as root.

HTH, gnasch
