    How to remove Compcache

    For those of you who don't know what CompCache is, here's what it is: http://code.google.com/p/compcache/

    Essentially, it allows systems with weaker specs to run Ubuntu without any major hickups (lag). This is good for a Live CD. However, since I've installed Ubuntu, I wish to remove it.

    Any ideas as to how to remove it?

    I found this solution, but at the moment Im not sure it resolve the problem

    Code:
    https://lists.ubuntu.com/archives/ubuntu-users/2009-February/174065.html

The following little script may be helpfull:

---8<--- swapreset ---8y---
#!/bin/bash
#
#     Filename : swapreset
#      Version : 0.1
#         Date : 07-feb-09
#       Author : email.listen at gmail.com
# Last changed :  07-feb-09
#
#      Options : none-yet
#        Usage : swapreset
#                

## test for compcache
## if yes reset swap and remove compcache and it's child kernel modules
if [ "$(lsmod|grep compcache)"  ] ; then
	## restarting swap, 
	## compcache will _not_ restart
	echo -e "currently aktive swap partitions:"\n
	echo -e "--------------------------------"\n
	sudo swapon -s
	echo -e "will now reset swap partitions"\n
	sudo swapoff -a
	sudo swapon -a
	echo -e "--------------------------------"\n
	echo -e "finally aktive swap partitions:"\n
	sudo swapon -s
	sudo rmmod compcache
	sudo rmmod lzo_decompress
	sudo rmmod lzo_compress
else
	echo -e "no compcache loaded! \nnothing to do so far."
fi

---8<--- swapreset ---8y---

Save this file to a users $HOME/bin/ directory who has sudo privileges.


Make it executable with:

    sudo chmod 700 swapreset

Start it and compcache is disabled.

    Re: How to remove Compcache

    seems that there is a bug .
    https://bugs.launchpad.net/ubuntu/+s...y/+bug/328437/

    to check if this the problem ,run...
    Code:
     sudo swapon -s
    ramzswap is also list along with the regular swap.

    on further reading that mailing list>https://lists.ubuntu.com/archives/ub...ry/174405.html
    Problem is solved after deleting /usr/share/initramfs-tools/conf.d/compcache
    and a:

    sudo update-initramfs -u

    rather than reseting the swap, deleting the above compcache file solves the problem...
    the compcache seems to be activated at every boot!

    after deleting the file ,to check , after reboot
    Code:
     sudo swapon -s
    this time the swap does not list ramzswap...

    Re: How to remove Compcache

    Many thanks for that!!

    My laptop has frozen 6 times since 9:04's been released!

    Lucky I was in tty1 when it started to freezr and i seen the "compcache" errors flying up the screen!
    That's when i notices my cache was 254Mb bigger than i had set.

    Quick google and i found this.
    Hopefully once the ram swap has been removed my system will be happy!
    Laters...

    Could you tell from "free -m" before and after if it actually freed the RAM? I assume if you're getting it out of vmlinuz and init.rd that it would.

    this is my output now... but didnt check before
    Code:
    $ free -m
             total       used       free     shared    buffers     cached
Mem:          2012       1555        456          0        162        636
-/+ buffers/cache:        757       1254
Swap:         3467        320       3146
    but i'm pretty sure that my swap was not used untill i removed the compcache[ since i used to monitor the swap/memory activity with conky]
    even though my swappiness was set to 100 ! it kept trying to write to the ramzswap and since it wasnt able to, my memory was getting bloated...

    but after the compcache file was removed, swap is used ... sparing my memory...

    Lightbulb Re: How to remove Compcache

    In case you are using non-default kernel or have generic and architecture-specific kernel, e.g.
    Code:
    2.6.30-1-generic and 2.6.30-1-386
    you should run update-initramfs like this:
    Code:
    sudo update-initramfs -u -k `uname -r`
    which updates initramfs image for the kernel you currently running.


    If you update image other than current the ramswap is still present in
    Code:
    sudo swapon -s
    output after reboot.
