When I open many tabs on browser, UI completely freezes. In some cases I press Ctrl+Alt+F1 twenty or thirty times, after 15 minutes UI unfreeze, I switch to text terminal, kill browser and after that operating systems work fine. In other cases UI freezes completely, I'm not able to switch to text terminal and I have to reset my computer.
I'm experiencing difficulties in one of these browsers:
- Firefox with flash plugin enabled (firefox without flash works fine)
- Google Chrome (it doesn't matter if flash is enabled or disabled in Chrome)
When computer freezes I don't see any strange errors in syslog.
Chrome, Firefox and Flash work perfectly on my computer in Windows 7. I have no freezing issues in Windows.
My configuration is:
Now I use Linux Mint 17.1 64-bit.
CPU Intel Core i5-4440 (with 4 cores)
Samsung 840 EVO 250 GB SSD
I have 2 videos: Intel HD Graphics 4600 and GeForce GT610.
Swap is disabled
CPU cooling works perfectly
Memtest show no errors
In the past I had same issue with Google Chrome on different computer:
Back then I used:
Scientific Linux 6.3 64-bit
Intel Pentium E5500
4 GB RAM
On that configuration Google Chrome was also freezing X server. If I remember correctly, flash in firefox didn't freeze UI on my old PC.
How can protect myself from UI freezing? Should I change some linux config file to avoid freezing? What is the reason of freezing?
