Ubuntu 10.10 starts to have mini freezes every 2 seconds. If I am typing in any sort of input (for example the terminal or a text field in Firefox or a text editor), I can type a few letters and then the entire OS will freeze for about half a second and I will lose focus. I can then (if I'm quick) click back into the input and continuing typing before it freezes again.
This will continue until I try and do something like close Firefox, kill/start a process from the terminal or save my work from a text editor. At that point the entire system locks up and I have to force the virtual machine to close.
I only experience this if Ubuntu has been running for some time with a minimum of roughly 1 hour. I am running Ubuntu as a guest on Virtual box (version 4.0.4) from inside a Windows 7 host. Windows itself does not freeze or become inoperable at all during this time.
The only thing I can do is to restart Ubuntu and get as much work done before it decides to freeze again. Very frustrating.
What steps can I take to solve or further troubleshoot this problem?
Following Takkat's instructions, I was already doing the following:
- Had VT-x/AMD-V enabled
- Latest version of virtual box
- Guest additions installed
- Disabled 3D acceleration
- Enabled nested paging
- RAM set to under half of total system RAM (3GB out of 8GB)
In addition, I did the following:
- Disabled screensaver in Ubuntu
- Reduced cores from 2 to 1
- Increased Video memory
This seems to have completely fixed the problem. Thanks!
