Kernel gets updated too often on ubuntu 12.04

0 votes
373 views

I am running Ubuntu 12.04.2 and run the updates manually on a regular basis from the command line. I noticed that the Kernel gets updated too often...
I know I am supposed to reboot the machine after a Kernel update, but that means rebooting every two days. One of the things I like to do is run the uptime command and smile :-)
1. Why does the Kernel get updated so often?
2. How do I find the change log, so I can decide if I need to update / restart the machine?

at Kubuntu 13.04, the kernel updates you point at, come in as well quite frequently ever since a few weeks. However, it do not interrupt a work session. it carry out each update; but rebooting can wait till the next break or till the end of a working session.

I have switched my laptop to Ubuntu 12.04 (14.04 was not out then) from Windows XP. Everything works great except for two things:

Google Earth does not recognize his on-board VGA adapter (Intel 945) as capable to manage 3D textures. and I cannot get his old Lexmark x2620 printer to work. Can anyone suggest some pointer.

I noticed some time ago the Cog icon on the top right on Ubuntu 12.04 stopped turning red after I run an update that requires a restart (like the Kernel).
1. Why?
2. How do I fix it to get it back?

I am thinking of upgrading from 10.04 to 12.04, just a click away in the software centre (no particular reason other than to benefit from recent fixes and continued support).

There are probably no easy answers (though I'd like some brief ones), but I wonder how common soft/hardware in/compatibility related problems are, resulting from such an upgrade?

Also, I am assuming all custom configurations will remain unchanged after such an upgrade (default email and custom settings, www browser bookmarks, various .rc files, repository settings for auto upgrades of unsupported software, and such), please correct me if should not assume so.

We have tried to do build with the normal user, but it failed after some time without giving any permission issue. I have made compilation directory permission as 777 and the same code has been compiled successfully with sudo or root user.
