PCLinuxOS is fast, uses a light X11 interface and works well in older

[SLUG] mysql error

[Ashley Maher]

Any help appreciated.

My MYSQL Server is dying with:

key_buffer_size=16777216
read_buffer_size=262144
max_used_connections=14
max_threads=151
threads_connected=5
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads =
133314 K
bytes of memory
Hope that's ok; if not, decrease some variables in the equation.

I'll bet your issue is 3D graphics

I have and do do and do like fvwm. If that is a bit daunting (use the editor 
luke) try mint 12

Not able to offer any comment on android.

Re: [SLUG] Android for "work"

[Mark Walkom]

Did you try XFCE or something a little more light weight on the GUI front?
Or even disable all the default fancy stuff.

I am still running 10 and gnome 2.3 and don't have any issues on a laptop
at least 4 years old, looking to upgrade this weekend to 11.something and
XFCE.

Re: [SLUG] Android for "work"

[David Lyon]

maybe 2 years is really 5 or 6..

Actually, I just jumped over to learn Puppy Linux. Pretty hardcore
but everything is quite good. Ubuntu has nice graphical effects but
I have work to do and willing to lose them in an effort to get some
stuff done..

still curious about Android..

Curious... My two year old hardware is just fine on 11.04

I just installed 11.04 on a R50 thinkpad for a friend and it was 
perfectly acceptable.




So, there is Android 3.2 from:

  http://www.android-x86.org/

Any good for tech work? ie light development, modding websites, ftp, python,
databases etc.

I notice it has dosbox, geany and most of the other tools are ported.

Re: [SLUG] Solid State Disk Works Okay with Linux on Kogan Laptop

[Jake Anderson]

On 12/12/2011 09:27 AM, Tom Worthington wrote:
I dropped my Kogan Agora 12 Inch laptop onto a stone floor. Remarkably 
there was no damage to the case or screen (the screen was open at the 
time and the computer running). But the hard disk was not functioning 
afterwards, so I replaced the 2.5 Inch SATA disk drive with a Solid 
State Disk (SSD). This turned out to be a useful upgrade: relatively 
easy and inexpensive.


Kogan offered me a 30GB SSD, as provided in one model of the laptop, 
but I decided on a larger 60 GB unit, costing 50% more for twice as 
much storage.


Replacing the disk drive required me to un-clip the battery from the 
back of the laptop and remove one screw holding a small panel over the 
disk drive. The disk then slid out and I slid the new SSD in. The new 
disk was completely blank so I booted the computer from a USB flash 
drive with a copy of Ubuntu Linux on it and then partitioned the disk 
with that and installed Linux. This took about 20 minutes.


After installing Linux, about 40 GB of the disk is available for data. 
As I just use the computer for taking notes, the smaller 30 GB disk 
would have been adequate (with Linux taking up about 20 GB), but the 
extra space may be handy.


The computer seems to boot a bit quicker but otherwise is no different 
in operation. I am yet to see if the battery lasts longer with the 
lower power storage device.

double check your file system has options appropriate to make use of 
TRIM, my understanding is its done at that level and not taken care of 
automagically (at least not yet)
with no trim once you have written 60gb of data to the disk (even if you 
delete it later, or overwrite existing data) writes will become very slow.
