Hello everyone,
I was always a Windows user and started using linux 2 weeks ago, I'm still learning.
The first distribution I installed was LMint Xfce 19.3 (compatibility mode), but I noticed a slowness, probably caused by my PC hardware.
Processor: Intel Pentium 4 (Northwood) 2.60 GHz
RAM: 2 GB
HD: 146 GB
Monitor: AOC LM522 [Cod. TFT1560PSA] 15 inch LCD
No additional drivers available for download.
That's why I switched to Xubuntu 18.04. In the system live by the pen drive everything was fine, but when installing it permanently, the resolution of the monitor got problems. I searched some sites and could not solve using the command xrandr. The current resolution is 640x480, but my monitor is 1024x768.
The terminal response to the xrandr command is:
Code:
gustavo@gustavo-STI:~$ xrandrxrandr: Failed to get size of gamma for output default
Screen 0: minimum 640 x 480, current 640 x 480, maximum 640 x 480
default connected 640x480+0+0 0mm x 0mm
640x480 73.00*
gustavo@gustavo-STI:~$ cvt 1024 768

Using the command lshw -c video, your answer was:
Code:
gustavo@gustavo-STI:~$ sudo lshw -c video *-display DISPONÍVEL

In lspci, one of the results is:
Code:
01:00.0 VGA compatible controller: VIA Technologies, Inc. CN700/P4M800 Pro/P4M800 CE/VN800 Graphics [S3 UniChrome Pro] (rev 01)
I also created the xorg.conf file with the code:
Code:
sudo Xorg :1 -configure
and sent it to /etc/X11 without changing with the code:
Code:
sudo cp xorg.conf.new /etc/X11/xorg.conf
I restarted and nothing changed.
What can I do to fix this problem?
Best regards,
Gustavo
