I'm new for linux, but I had some occasion to use different versions of it on other PCs or live-CD on my own PC.
Yesterday I decided to normally install Ubuntu on my desktop computer after several sucks with Windows 7.
My problem is, that the installed system is very slow, slow response time (destop search delayes 1-2 seconds when I type characters!), the videos (in youtube) are slow (others not yet working), etc. ANd the window in the Gnome/Kde (default) environment is slow by moving, resizing, opening, closing, etc.
The system has following parameters:
- Amd X2 processor (64bit) dual core at 2.3 Ghz
- 2 Gb system memory (therof 1,8 Gb usable due to integrated AMD/ATI X1200 series video card)
- Corsair SSD accelarator (used as single SSD without HDD), read / write is about 200/ 150 Mb/sec.
Default install and updates from internet was done. The processor use in average is about 70-95% each, without running nothing. In system monitor I see a kind of graphic program running and consuming 30-50% CPU time in average, if I close this the desktop tray and icons disappers and CPU useage fall back ca 20-30% per core each (but nothing works after it).
What could be the problem? How I could fix it? Now this Ubuntu is slower on this computer as a Windows 7 on a 10 years laptop.... Ubuntu version is 14.04, the latest.
I checked a kind of system properties and drivers panel, it is said up to date.
Thank you for your help!
