SOLVED - After trying to fix something which wasn't broken......

[Maurice]

My machine was runnjng a bit slowly on memory intensive stuff like Google Earth so I opened it up and reset the memory cards and checked a few other connections. When I put it back together I found I couldn't get into my Pclos (updated). I could get into XP and Solusos but not Pclos.

I entered dmesg |tail from Solusos and got the following -

felix maurice # dmesg | tail
[  238.598673] Descriptor sense data with sense descriptors (in hex):

Have I fried it? Can someone kindly make sense of this to me please?

Thank you

I would first fire up my PMagic LiveCD and do a file system check. Then try again.

A remaster with Gparted on it could be used as well of course.

Are both OS's on the same drive? If PCLinuxOS is on it's own drive maybe you've accidentally nudged a cable.

Have you checked the HDD cable(s) and tried reseating the ram modules?

And as a "just-in-case" you may want to boot the LiveCD and backup any important data/settings etc....

Thanks for the replies. I don't have PMagic willem - I usually use Gparted and, of course, can't get at it. And no remaster.

Yes menotu all are on the same drive, I reseated the four ram cards and double checked the HDD cables. I had only updated Pclos last week and have all the settings I need well backed up but thanks for the warning.

[Just17]

Use a PCLOS LiveCD/LiveUSB and do a file system check on the PCLOS partitions.

man fsck

for info

[djohnston]

Start with booting from a PCLinuxOS live CD. Run a filesystem check on sda3.

su root
umount -a
fsck -fy /dev/sda3

You will get an error that / is busy after issuing the umount -a command. That is normal.

[Maurice]

Thanks DJ and Just18. Will do that.

[Maurice]

Well, well, I never expected to get this fixed before I turned in for the night.

I ought to know about fsck by now - I've used it before but didn't give it a thought.

Many thanks chaps, I really appreciate your quick and helpful replies.

Glad it was that simple, Maurice.

Glad it was that simple, Maurice.

Me too. Wish they were all that simple. Still left with the problem of a sluggish Google Earth but I'll bring that up in another thread.

Hi Maurice,

"sluggish Google Earth "

Found these two complimentary items (see if they work for linux):

How To Fix Slow or Sluggish Google Earth Not Responding Windows 7

Open Internet Explorer, select Tools->Internet Options
Click on the Connections Tab
Click on the Lan Settings button
Uncheck the Automattically detect settings check box
Click the Ok button
Restart Google Earth

This fixed all of the slowness issues I had with Google Earth 6.1.0.5001

Thanks Phil. I don't have I Explorer. However I solved the problem by going to Tools/Options in GE itself and speeding up some of the settings there, many of which are set at low defaults. There was also the facility there for clearing the memory cache and the disk cache. It then worked as it should, all the sluggishness gone.

It seemed a bit too easy though and, from my searching, I found that it is a very common problem on all platforms, but I hope that the improvement I got is permanent.

[Maurice]

But    -- on starting GE again it was back to its sluggishness.

So, back to searching and I finally found the answer and it's simple - just disable Desktop Effects. The effect is immediate and the speed makes it usable once more.

After doing this I have opened Earth five times and it works each time.

I hope this helps others who are having the same problem.

[aguila]

IIRC, there's a widget to toggle desktop effects. Maybe a nice addition - turn off when starting GE, turn on when finished.

Dunno if they can can be turned off on the command line, in that case you could even turn them off via the command when hitting the GE icon.

Just an idea though.
