#Ubuntu is surprisingly unresponsive compared to Windows. Launching programs can take 5-10 seconds (with no indication that anything is happening). Resizing a window sometimes resizes the frame and then takes a second to fill in the contents. Even the internet seems slow to respond.
Some of this might be due to the fact that Ubuntu is running off a physical hard drive while Windows was running off an SSD, but that doesn't seem sufficient to explain it.
I would have expected to get *more* performance without Microsoft constantly uploading data. Does this match anyone else's experience? Any ideas?
@peterdrake Slow desktop drawing could be GPU related. What type of machine is it? Specs?
@popey It's a Corsair One. Intel i7 (12 cores), GeForce GTX 1080 Ti
It's lightning-fast under Windows.
@peterdrake I wonder if you have the binary nvidia driver installed or not? There's an application called "Ubuntu drivers" which you can use to install them. Once done, reboot, and then login with an Xorg session (click cog in bottom right of login screen). Suspect it will make a difference
@popey $ sudo ubuntu-drivers autoinstall
All the available drivers are already installed.
(And why on earth wouldn't Ubuntu have installed them when I installed it ten days ago?)
Some variant of "the graphics system is confused" does sound like a reasonable hypothesis. I'll reboot and see if I can find that cog...
@popey I see no such cog, but does this mean I'm already in xorg?
$ ls -l /usr/share/xsessions
total 8
-rw-r--r-- 1 root root 292 Apr 7 2022 ubuntu.desktop
-rw-r--r-- 1 root root 300 Apr 7 2022 ubuntu-xorg.desktop
@popey I don't understand what you're saying / asking, but here's the output:
$ env | grep SESS

@peterdrake session type x11 is xorg as opposed to wayland so it’s not that.
