Linux Mint Forums

I have Mint 13, Maya for almost a year. I like Mint, but I have 2 or 3 small problems.
The biggest problem is that when I play video (any format, any player, both on my hard drive and on Internet or Youtube), then it often freeze and sound will loop (short part of the sound, maybe half second) until mouse or keyboard activity. I can resolve the problem if shift is pressing (holding down, leave something heavy on the shift button). I don't know the reason for this.
Before Mint I did use OpenSuse and I did have the same problem there. But in OpenSuse I was able to log in to some-kind of fail-save mode and there I didn't have this problem. I often think if that is possible with Mint, or if there is other solution for me.
Another problem is that sometimes keyboard is typing 0 (zero) by it self. I did have that problem in OpenSuse too. I have tried to replace the keyboard but still the same. I have even tried to replace the mouse. This just happen sometimes and seems to differ between logins, so sometimes when I turn on my PC I will only be able to type 2-3 words between I get one or more 0, but next boot I don't have any problem. If I open any text editor (or any programs or web-sites that have some inputs field), and just keep it open, without touching the keyboard, then soon there will be lot of 0000000's there. This is only in Linux, but not before the Linux boots (and not in windows). I have search this (google) but only found one Windows related http://www.computing.net/answers/hardwa ... 85341.html and I don't know how to find out if I have two or more installed keyboard in my Linux OS.
There is other problem with my laptop (cannot use USB keyboard in Linux), but probable I will have to put that question to new topic (different computer).
Here is some info about my Desktop

I think I have solve this for a moment (just few days ago). I can play video and now the video seems to play without freezing. The blinking-cursor is now blinking all the time too (the cursor did often stop blinking).
I think this is not the best solution for everyone, because I think I will not be able to use the full future of the graphic card. But it is enough for me. because I am not using the desktop for playing games and I don't need all the speed and possibility's that the card have. The very most graphical activities I use, are playing some music videos and cartoons for the kids. This is enough for me.
The thing I did is to find what exactly where the parameters in the OpenSuse failsafe OS (I did use OpenSuse before mint and OpenSuse have failsafe mode and in that mode I didn't have this freezing problem).. I then look at the parameters and try to image which of them can possible be related to graphic.
In Linux Mint Maya I did then type in Terminal (this probable differ with other Linux-flavor, most of them using gedit) sudo pluma /etc/default/grub

There I change the line GRUB_CMDLINE_LINUX_DEFAULT to GRUB_CMDLINE_LINUX_DEFAULT="nohz=off highres=off processor.max_cstate=1 nomodeset x11failsafe"

and save and close the text editor. Update the grup with sudo update-grub

And restarted the desktop. Seems to work now. I don't know exactly witch of the parameter did do the trick but I think I will check that later (at the moment I am quite busy).
Now the desktop boot quite quickly (before this the desktop did take it time to start, from long time to very very long time, sometimes more than 10 minutes).
I still don't know the reason for this, but happy that I have good working desktop again.
Only thing I still need to find out is why my keyboard sometimes start to type 0 (zero) by it self. It is nothing wrong with the keyboard (I have tried replace the keyboard). But this is minor problem.
