FAQ wrote:

-- Love sources FAQ --
Orginally written by: Love-sources team
Revision by: predatorfreak

Q: I have a black-sreen freeze after startx
A: Please try and compile the kernel without vesa-tng support enabled (built-in/module).

Q: Why Ingosched is in Love-Sources now ?
A: Ingosched has the most testing because is tested by all vanilla users.
It is also defulat Linux 2.6 CPU Scheduler and it is pretty stable now.
Ingosched development also doesn't sleep, look into -mm tree for example.

Q: How to use the RT rlimits patch for Linux Audio?
A: please follow this nice how-to -> http://www.steamballoon.com/wiki/Rlimits

Q: So, where did Reiser4 go?
A: Away

Q: Why?
A: A number of reasons, the love sources team strive to bring you the
best desktop experience and Reiser4 can greatly degrade interactivity and
increase cpu usage. It's illogical to have a CPU Scheduler oriented towards reduced
latencies and filesystem with high latencies.
It's also operating under several wrong assumptions on things
like page table sizes. Reiser4 also doesn't support architectures
aside from x86/x86-64 and doesn't run on the 4kb stack size.

Q: So now that love-sources isn't going to support Reiser4 what do I do?
A: Compile one of the great number of Reiser4 enabled kernels, like
Andrew Morton's mm tree, which is even in portage.

Q: Why are you pulling Reiser4, it's the base of Love-sources?
A: Actually it's not, when love-sources started it was in large part to
research how to allivate the famous music lag bug. A bug that Reiser4
ironically introduces again.

Q: Okay so I shouldn't use Reiser4, what then?
A: Ext3 with dir_index is a much better universal filesystem for a desktop since
it performs nicely and has really good latency. Aside such likable
qualities as stability , it has been developed for "ages" in comparision to Reiser4.

Q: I'm an ext3 user, but how can I check or enabled the dir_index feature?
A: Please check if you have it in the superblock by using this line:
1) my_box# tune2fs -l /dev/hdaXY
if You should receive a line like this one with dir_index enabled:
Filesystem features: has_journal dir_index filetype needs_recovery sparse_super
then you have it enabled.
if not, please use:
1) tune2fs -O dir_index /dev/hdXY
2a) updatedb
or
2b) e2fsck -D /dev/hdXY

Q: I'm a Laptop user, I want to increse my battery life-time, what should I do ?
A: Use JFS as your filesystem, It has less cpu usage (definatly better than reiserfs/reiser4)
and your battery lifetime will be increased up to 30% more then reiserfs/reiser4.
In Love-Sources there are also up too date fixes for it.

Q: Okay, I'm interested in better interactivity, I can resign from using reiser4 for this.
Now I'm using other filesystems (we recommend you use ext3+dir_index).
Which IO Scheduler should I use?
A: Please try the CFQ-TS IO scheduler (default in love-sources).
This is a Completly Fair Queuing IO Scheduler which gives you optimal destkop interactivity
even in heavy filesystem usage.

Q: What about Nvidia and Ati fixes?
A: In the current love there are no Nvidia or Ati fixes.
Please use Driver side fixes from the net (there are many fixes).
If you're an Nvidia user, Many of the good fixes are in Gentoo Portage.
minimum kernel driver required to run this release is nvidia-kernel-6629-r4.

playfool's guide to make ATI work:
1) get the ati source code GPL'ed
2) enjoy a working driver
(for the guide to make nvidia work, just replace the word ati with nvidia)

You can download just this http://vivid.dat.pl/fallow/2.6.12-love1-upd01.diff
copy it to /usr/src/linux-2.6.12-love1
and in /usr/src/linux-2.6.12-love1 dir do :
patch -p1 < 2.6.12-love1-upd01.diff
and recompile and install new bzImage.

or delete 2.6.12-love1.bz2 from distfile ,delete digests . regenerate & reemerge.

new patch on the server contains the fix :)

cheers :)

Sweet then, well When I had posted this I had just d/l the ebuild (like 30sec before)

I have just emergd bootchart and have taken the data from that.
Going to compile loveSRC now and do bootchart on it,
equally gonna check out that new INIT system

find out (via) boot chart what boots best.

@fallow: with this release my http, irc and pop3 connections don't work any more, but my Y!messenger and skype ones work; i didn't have time to test others

i messed around with the networking options, but to no avail, i even dubble cheched my firewall rules 8O just to make sure :x , hope the next release will be better

p.s. i also tried using both low-latency desktop and pre-emtetive desktop :x

please take careful note that suspend2 is not a supported patch, thus applying it voids all tech support.

yeap , please dont post here about swsup2 , we are not supporting it at all and its not in love.

for swsup2 use latest nitro for example , which contains swsup2 .

teutzz: what about 2.6.12-mm1 and your networking problems ?

cheers.

what networking problem, fallow?
I've noticed, that when I'm using genetic i/o sched, my network connection dies after several minutes (after random period of time). Interface is up, but I cannot even ping my router or any host in LAN. I've got Realtek 8139 NIC on rtl8139too driver. After switching to cfq everything with network seems to be OK.

Are you by any chance using the Anticipatory IO scheduler, I'm very interested in getting some real life data on that one.. especially if you can reproduce the issue cited above.

my curiosity is extremal now :)

I dont see any connection beetwen io scheduler and networking problems

Im using cfq,deadline,genetic and non-genetic anticipatory without any problems.

the only thing I can guess is that the networking problems can be an effect ot TCP* patches.

Will be reversed in next release then.

cheers.
