This command line threw me something like the following: # 1280×1024 70.00 Hz (GTF) hsync: 63.00 kHz pclk: 96.77 MHz

Now it is important to check what resolutions our monitor can support as well as what frequency it works on.Īlready investigated this, with this data we obtain them with this syntax: gtf 1280 1024 70 In the first step we are going to enable one more resolution to our monitor settings, first we verify the option we want to have with our monitor and our graphics card, in my case I am interested in enabling 1280 × 1024 resolution. In this case we must have all the monitors that we are going to use or if it is only one we have no problem. Within of the most common problems that I encountered when I first migrate to Ubuntu was the topic of screen resolutions and a few additional hardware detection issues, I'm talking about 10 years ago, I had a gaming rig back then.įor this I used 3 monitors and used the ports of the graphics card and additional to it with the port of the motherboard, which in Windows is possible more without on the other hand in Linux I have not been able to do it.Īnyway it is not something that requires for it as many of you will know, all possible resolutions are emulated in Windows while on Linux only the right ones so to speak so when I wanted to make mirror screens I ran into a big problem, since when using the VGA ports it only displayed certain resolutions while with DVI and HDMI other things that I generate conflict.įor this I found Xrandr a small tool that helped me solve my problems.
