I recently installed Ubuntu 20.04.03 on my PC. When I ran the installation, it worked well, initially. However, after I shut the computer off and turned it back on, I get the login screen, I typed my password and it hung on the purple screen. It is just a blank purple screen. I browsed the web and found that it could be the Nvidia driver causing this issue. For this reason, I removed my graphic card and ...

I wanted to use daisy chaining to connect two monitors to one usbc thunderbolt port (three monitors in total).

In principle it works, but I can only get the second monitor in the chain to mirror the first and not extend it. Neither gnome, nor nvidia-settings recognizes the second display in the chain.

The monitors are all Dell UltraSharp 27, the MST option is activated on both monitors, the error oc ...

I've been using wayland with intel 520 graphics and, for the most part, it works excellently. However, I noticed that any hardware accelerated 1080p video playback (VLC,MPV etc) causes stuttering, not just in the video, but on the entire desktop (for instance, pressing super to see programs side by side with be stuttery).

I also noticed that, unlike with XORG, when video is playing played, the gr ...

I'm facing problem with xrandr to set new resolution and refresh rate. I only have the resolution 2560x1440 with refresh rate 33 mhz, if I try to increase the refresh rate I got the error below:

I recently purchased a Lenovo IdeaPad 5i Pro (16IHU6) with the following configuration

• CPU: i5-11300H

and I fail to run Ubuntu 20.04/21.10 (to be honest, any Linux so far) on it, without having serious screen issues (both, using the integrated and dedicated graphics card).

I have a monitor. The hardware can support 1024x768 at 85Hz. But don't know why my lubuntu system does not detect this highest refresh rate for the resolution mentioned above.

I'm new to Ubuntu and Linux with a GUI in general. I just installed Ubuntu on my new Dell XPS 13 2in1 and immediately noticed stutters when scrolling through the Terminal or Firefox.

I am thinking about buying a new Lenovo laptop which uses the Intel® Iris® Xe Graphics. I am not seeing anything here on that driver and 21.10 and if it works out of the box. I am currently using a laptop with AMD graphics which does not work with 21.10 and no additional drivers are found in software/additional drivers. Is there a list of supported graphics somewhere? Thanks in advance. Bob

Hi, I've been using Ubuntu for about a year now and have just bought a new laptop. I installed Ubuntu once again along side Windoze 11 on separate partitions.

When I move my mouse fast it causes the panel to blink (rapidly disappears and appears).

When I move the mouse slowly over panel it does not blink.

Probably this is related to render of window contents.

I am having an issue watching hd (720 or 1080) videos on Ubuntu 21.04 fresh install. I get really high cpu usage (50% on all cores) which is pretty high for a 720p vid. I tried watching the same video on vlc (hw acceleration) and it works perfectly fine. I even tried a 4k video and it works fine cpu usage < 20%. Why is chrome consuming so much cpu?

I have two 27" monitors running 2560 X 1440. Resolution is fine, but when I scroll any webpage in any browser, it streaks. The update drivers in the software module didn't show anything new. Intel graphics card btw. Any ideas/tips? I'm not new to ubuntu, been running it on a laptop for awhile, but recently made the switch from windows on my main PC.

I installed 20.04 on an HP laptop with Intel iris(xe) graphics adapter, dual-booting with Windows. The screen starting flickering after an update. I've read a number of suggestions and none seem applicable to me. I haven't tried Wayland, but it seems to me that the flickering starts before the X server is loaded. What works for me is to boot into diagnostic mode, and then continue to a normal boot.  ...
