Can't set a new resolution on Ubuntu 20.04

us flag

Okay, I've been using my laptop connected with a external screen which is 2560x1080, try to add the new resolution and set up. But always return xrandr: Configure crtc 1 failed. Also checked my CPU max resolution on HDMI and it's 4096 x 2304@60Hz, don't know what else to do. The commands I use was: xrandr --output HDMI-1 --crtc 1 --mode 2560x1080_60.00, xrandr --output HDMI-1 --crtc 2 --mode 2560x1080_60.00, xrandr --output HDMI-1 --mode 2560x1080_60.00 but always return failed.

Its weird cause it shows 2560x1080 in the GUI, but still don't set for the 2560x1080, always reverse.Resolutions options

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.
