comment Swap utilization: system level versus individual processes
@Max What top reports is all of the memory (by type) used by all of the pieces used by the program. If program P uses shared libs A & B, then then P's memory usage in top is reported as the sum of the memory usage of P, A, and B. If you also have program Q using lib A, Q's memory usage is reported as Q + A. Thus if you add all of the memory usage in top for a system only running P and Q, you are actually seeing the memory of P + Q + A + A + B (in other words, some of the stuff is double counted!).

comment Bad performance with ATI Radeon X1300?
Looking at help.ubuntu.com/community/RadeonDriver indicates that the r300g is probably a good choice for the X1300 card. (I had similar problems with an X1250, which of course likes the r600g driver.... go figure.)

Here are a couple of pages that may help with the particulars of handling the smb (or cifs) credentials: knoppmythwiki.org/index.php?page=Autofs+and+samba and howtoforge.com/accessing_windows_or_samba_shares_using_autofs .

After scanning this question I decided to try the package myself, and I am impressed with the decrease in the time to hibernate. Thanks.

comment Video player with good subtitle rendering
I started my reply, got a phone call, submitted, and then saw all the comments.... LGB should get the credit... I always use mplayer through the CLI, but you may want to check out gnome-mplayer, smplayer, and kmplayer from the Ubuntu repos.

comment How to tweak Ubuntu running on an old PC?
Sounds slightly hotter than my MythTV frontend (P3 1GHz, 384M RAM). I run Ubuntu 10.04 on that without too much problem, but it really mostly for MythTV and some lightweight gaming.

comment Connect to NFS on availability
My experience with banshee looking at music on an automount is that whenever banshee looks at the drive, it is there, so it never misses the directory. (That's the point of automount.) The only exception is when the server crashes or the network goes down, but that would happen to any remote mount and has been very rare.

comment to clone a filesystem from a remote system to a local HD
That's because /dev/hda1 is a block device and doesn't look like a file (at least to rsync). Assuming / is mounted on /dev/hda1 (doing df should tell you), you should be able to do "rsync -cavzpx admin@X.X.X.X:/ /home/user/Desktop/backup/" (I think it will 'do the right thing' with /proc and /dev.) The -x tells it to stick with the disk it is on.

comment How can I get an nfs mount in fstab to use the bg option to mount a server when it eventually comes up
I'm not sure why you would need symlinks to /net. Autofs can be setup for auto-mounting anywhere. For example, I auto-mount several shared drives to common points on the Linux boxes on my network: one goes to /mnt/public, another to /var/lib/mythtv/recordings, another to /var/lib/mythtv/videos, etc... These are all defined in auto.data. I never use /net unless I am doing a temporary or one-time mount. As for load, I am not convinced that this will cause that much of an increase, but YMMV. It's old tech from the days when 256Meg was a lot of RAM.

comment Can't find Windows after installing Ubuntu
If there is data you want off the former Windows install, STOP USING THE COMPUTER NOW and find another one (at a friends or a library, etc.) The more you use the computer, the more chance of overwriting stuff.

comment What are full partition/disk imaging solutions that produce mountable images?
There are some ways to get at the contents of the image without restoring it to a physical drive. I've updated the answer with what I know.

comment How to shrink Windows partition with unmovable files in dual boot installation
The files are probably in use, so you can't move them. I think you may need to do a defrag before windows is up and running. I don't think the bundled version that comes with windows probably does not support that (in XP and older it was a defeatured commercial product), but there are some commercial ones that do. Diskkeeper and PerfectDisk come to mind, but there are others.

comment All video players display black screen
I'm at a loss. The best suggestions I have is try re-installing the drivers or trying the non-proprietary nv driver. If the problem is still there with the nv driver, then it is most likely not a driver issue. Good Luck.

Are you using the proprietary Nvidia drivers or the Xorg Nvidia drivers? Also, have you tried disabling Compiz or other eye-candy?

comment Solutions for cheaply replacing poorly-supported onboard ATI card with discreet graphics on desktop machine?
What you are looking for is cards that use the NVidia chipsets, even if they aren't made by NVidia. I have had good luck with several different brands. Bottom-end seems to be about ~$25 for a 2 year old chipset that will play most games (and even do VDPAU if you are in to MythTV). Top end? More than a new motherboard.

comment Best way to list 100 first files in a directory sorted by time
It's possible he may not be running ext4. I run Ubuntu 10.04 on all my machines, but run JFS on several drives. AFAIK JFS does support creation time stamps.
