Intel® HD Graphics 4600 (HSW GT2) 1920x1080 resolution not work

ar flag

I have a Intel® Core™ i5-4590 CPU which has an integrated Intel® HD Graphics 4600 (HSW GT2) GPU and I have installed Ubuntu 20.04.2 LTS with it.

My monitor resolution is 1920x1080 but Ubuntu just show me 1024x768 and 800x600 resolutions.

So I searched for solution and due to this answer I do as follow:

  1. cvt 1920 1080

  2. sudo xrandr --newmode "1920x1080_60.00" 173.00 1920 2048 2248 2576 1080 1083 1088 1120 -hsync +vsync

  3. sudo xrandr --addmode VGA-1 "1920x1080_60.00"

After that I go to display menu and see 1920x1080 is added, but when I choose it my screen freezes the first time with a blinking mouse pointer. I try it again and it just revert my choice after Apply and nothing changes.

I searched a lot and find some solution like removing xserver-xorg-video-intel package, or changing /etc/X11/xorg.conf which is not available anymore, that leads to nothing.

I will show more information, maybe leads you to solution.

xrandr:

I'll appreciate any suggestion. Thanks.

I had a similar problem and the modeline that I was using from `cvt` was wrong, in particular the pixel clock rate. Check the manual for your monitor.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
