Ubuntu 14.04 frequent mouse freeze

Question

I recently installed Ubuntu 14.04 alongside Windows 7 on my Asus (i5 core and 8GB Ram).

I experience frequent freezes of my screen. I cannot move the mouse, but I can use the keyboard. When it happens I could always open a command line with Ctrl+Alt+F2 and do sudo service lightdm restart to restart graphics.

But that of course does not fix the problem and is rather annoying since it happens rather often.

How I can find and fix the underlying issue here?

Greets and thanks in advance

Solution 1

I get it occasionally in 12.04 LTS. control+ALT+t will usually open a terminal window. modprobe -r psmouse followed by modprobe psmouse will usually fix it.

Check RAM by booting into GRUB. Boot holding shift down, then test memory.

Solution 2

Reinstall the mouse driver :

sudo apt-get --reinstall install xserver-xorg-input-mouse

Solution 3

This is maybe a process who reach 100% cpu usage a short amount of time? Install htop & look if a process is reatching 100% cpu usage.

This is something I encounter with multiple instances of vlc or some others applications.

Why did this question got downvoted? It's a legitimate question. I'm experiencing similar problem.

Check if your xorg get the mouse events correctly, login open a Terminal and enter: <code>$ xev</code> If your mouse freezes and <code>xev</code> doesn't show anything, when you use the mouse, then you have a driver issue.

Consider adding a bit more about what you think might be the problem and solution.

+1 This appears to have fixed the problem for me.

I guess this does not work for people who are not currently connected to the Internet?

i got unmet dependencies, of xorg-input-abi-20 and xserver-xorg-core(>= 2:1.14.99.902). Synaptic showed that xserver-xorg-input-mouse is broken. I looked at libevdev2, and it also had some broken dependencies and synaptic solved somethings for me, I am not sure what happened. My mouse is working at the moment, will update once I am sure

This seems to have worked in ubuntu 17.10. Having to do this every time when my machine first boots will be annoying
