Why does my laptop freeze

Post by brawnypandora0 »

Why does my laptop still freeze even after I formatted it and installed Linux Mint? Is it because I don't have enough memory?

Possibly, how much do you have? Look in the system monitor under the resources tab. Also look how much is being used and how much swap is being used?

Also can you post the output of

Code: Select all

inxi -G
as it can also be a graphics issue

1) It says 260 MB/433.2 MB (~60%). Is that a good or bad sign? I only use my laptop for a few basic things.

2) Swap is 69 MB of 1.2 GB (5%). What does that mean? What's swap?

Swap is a partition on your hard drive. It is used similarly to Windows page file. It is a place for the OS to store idle programs to reduce the ram usage and let active programs run.

If you have only 433 MB of available ram, your freezes could be caused by asking the OS to do to many things at once.

The 260 MB usage you show is more or less normal for a Gnome desktop at idle with the usual background programs running and maybe conky and/or a dock of some type. Opening any program will increase this number. If it gets high enough so you are using a significant amout of swap space it will slow your system down as read/write cycles to/from the hard drive are slower than to/from ram. Keep opening more programs or just open a few extra desktop windows, and your OS will get so overloaded it will essentially stop (it will probably be working, but so slowly it will seem to be stopped)

The best way to cure this is additional ram. If this is not possible (many older systems will only handle 512 MB or so) or not feasible for financial or other reasons, you must learn to close all running programs and windows when you are done with them and not overload your system with open apps you are no longer using.

AT beat me to it! but here goes anyway!

1) I think that amount of RAM should be fine, it may make for a not particularly fast experience especially doing many things at once but I couldn't imagine its causing freezes.

2) swap is when your computer has to use space on the hardrive, essentially once it has run out of RAM. This is MUCH slower than using RAM and can cause freezes. As your RAM is not close to capacity and your swap has a low percentage its pretty certain these can be ruled out.

personally, I'd imagine your graphics are a likely cause for the freezes, SiS have very bad (zero) support for linux, this thread http://ubuntuforums.org/showthread.php?t=1526038 seems to have some sort of success with a driver which someone has written, the instructions are a little fragmented but i think they make sense. If you want me to try to simplify them I'll do my best and write them up tomorrow!
