hello,

I have updated a Toshiba R600 from Centos 7.1 to 7.2 and now the display is
blurred (background, letters, ... but not menus) and time to time disk
manager (nemo) don't start.

if I reboot on the previous kernel (of 7.1 version) , all is ok

Any hint ?
The Centos Forum cannot help me.


With the new kernel 3.10.0-327 :

The original v3.10 kernel release is now 2½ years old, and you probably
have a pile of both longterm and distro patches on top. I'm afraid the
upstream can't help you much either.

Your best bet is probably to figure out what change between your kernel
versions broke things. If those -327 and -229 suffixes mean anything, it
might not be a huge task.

BR,
Jani.
