Install Linux on old computer

some weired expeirences:
1. elder version of Debian 7 did not work well with display. it displayed only a mouse cursor, and it could disappear easily afer moving it.

2. Ubuntu 15. it's super slow and crashed easily. it did not deal well with display as well.

3. Ubuntu 14. it displayed well but the wireless mouse and keyboard became not working.

4. Puppy linux. really fast to start and worked well. so it stayed on my usb key. I need to install an individual OS on desktop so that I kept trying new options.

5. Debian 8. starting from graphics installation since elder version was from text mode and appeared to eventually have graphic interface problem (this is not a good reason but that's how I made decision anyway). everything worked fine and smooth except sound. the solution is very simple:

try to reinstall  

apt-get install gstreamer0.10-plugins-base
apt-get install gstreamer0.10-alsa

maybe it is just to choose right output device in pulse audio volume control.

It reported that I was already using most recent ones and 0 was updated and nothing was installed. but it simply worked afterward.

6. check what video driver is using:

lspci -nnk | grep -i vga -A3 | grep 'in use'
