I want to use Linux to test PC hardware when Windows malfunctions. The idea is to boot Linux from a USB stick.
After initial experiments with Ubuntu, I decided to try Xubuntu with persistent partition. I prepare the USB stick using an Xubuntu ISO file and Rufus. I use a 32GB stick, and I set aside a varying capacity for persistent partition; I've tested 10, 5, and 4GB.
The results of the Xubuntu 24.04 tests are disastrous. Xubuntu boots, but response times are enormous. It takes a minute to open a terminal or to run ps or ls. It took around an hour to start Firefox. In the ps-e printout, a few processes have non-zero TIME, with Xorg consuming the most time, followed by systemd and firefox. The accumulated execution time of all processes after a two-hour operation is around 1 minute, but the system stands still.
The computer I'm using to test Xubuntu works normally under Windows.
Has Xubuntu 24.04 known problems? Have I missed something essential?
I have little Linux experience but many years of work with Unix, including delivering courses on Unix internals. But it was quite a few years ago.
