I've recently installed Linux Mint 15 on VirtualBox on a Windows 8 host. Everything seems OK, but I have severe problems with performance of Firefox on it. Sites display with delay and the keyboard input is horrible, I can write the whole query string in Google yet nothing is displayed in the browser (I use the website search engine, not that included in Firefox). Other program seem to work properly, although I just tested few of them that I really need (like terminal, Sublime Text and Firefox).
What's even stranger is the fact that I've installed a Windows 7 guest on another virtual machine with exactly the same specs and it works perfectly, no lags an problems. What can I do to fix this? Also, are there some tricks to make my Linux guest work smoothly?
The specs of my laptop: Intel Core i7-3610QM 2.30GHz, 16GB RAM, NVIDIA GeForce 660M on x64 Windows 8. And each of the VMs has this configuration: 8192 MB of RAM, 8 virtual processors and 128 MB of video memory.
Best Answer
1) Try to increase the virtual video memory to 1024mb (or set to max, can't remember the maximum allowed size) and lower the virtual RAM memory accordingly.
