To see if my GPU would be supported well enough i did a full test install to USB drive.
so the disk is a 16GB Toshiba drive, USB2.0, but among the faster ones
PC is:
AMD Athlon 64 single core, [WRONG! 3.2 Ghz WRONG!] EDIT: it's 3800+ 2,4 Ghz
4 GB DDR2 RAM
GPU: nVidia GT 730 2GB
OS: Kubuntu 16.04.1 LTS 32 bit (i actually wanted to test 64bit, but i forgot it was 32 bit that was on the DVD drive). i went with the .1 since the kernel in it stays the same for longer time.
Test: install to USB drive, update & install nVidia driver.
Live CD worked well and loaded relatively fast from the DVD drive. I installed it to about 14 GB disk space and gave it 2 GB of /swap (it was left practically untouched during the whole test...). The install finished in abotu 45 minutes which is to be expected with this older PC and USB drive that is much slower than SATA.
Then i did the updates through Konsole and it downloaded about 455 Mb of updates. it took it 4 hours to install that. the nvidia driver install took about 1 hour.
all this time system monitor showed CPU at 100% and everything lagged a lot. but top didn't show any major increase. also the system monitor itself accounted only about 30% of CPU use.
this was also the case after installing everything. the menus and such seem responsive, but once an app is loaded (e.g. Firefox, Kate) everything is slowed down a lot. i can't find what is causing the slow down. OK for the app to load slow the USB is at fault, but after that there is plenty of RAM being available... how could i find the process responsible for taking so much CPU?
here are the readings when CPU was used 100%
Top showed similar usage.
The CPU is used 6-10% or less (2-3 %) when on idle. probably something that is expected.
Another issue was that after installing nvidia drivers all fonts were huge, while the LCD monitor was recognised as CRT. i guess others have faced that and this is solvable.
