I would like to use the internal speakers. Can any one help me please, the Google searches all relate to ubuntu and not much help on Fedora Check your access to the sound group (audio and maybe pulse). Make sure you are not signed on twice. When I stack sign on (eg Ken then chris) the sound is assigned to Ken and Chris does not have access to it. Make sure your sound is not muted. This is a stupid default. I also had problems that it was always muted and I had to reset this on every sign on.

Re: [SLUG] fstab and simultaneous mount points

Have you tried it yet? :-) I have now. I'm getting erratic and unsatisfying results. Mostly it fails to mount. Always mounts on reboot. I can mount manually, so maybe since I always have to be there to put the hardware in, that's the solution. I'm not about to deliberately mount them both, so that one remains to be seen ;-) var/log/messages says: Feb 3 22:41:52 david kernel: [37287.337301] sd 3:0:0:0: [sdb] Attached SCSI disk Feb 3 22:42:39 david kernel: [37335.105748] EXT4-fs (sdb1): barriers enabled Feb 3 22:42:39 david kernel: [37335.118484] kjournald2 starting: pid 19625, dev sdb1:8, commit interval 5 seconds Feb 3 22:42:39 david kernel: [37335.118762] EXT4-fs (sdb1): internal journal on sdb1:8 Feb 3 22:42:39 david kernel: [37335.118768] EXT4-fs (sdb1): delayed allocation enabled Feb 3 22:42:39 david kernel: [37335.118772] EXT4-fs: file extents enabled Feb 3 22:42:39 david kernel: [37335.184901] EXT4-fs: mballoc enabled Feb 3 22:42:39 david kernel: [37335.184911] EXT4-fs (sdb1): mounted filesystem with ordered data mode but the disk is not mounted. I thought that these disks would mount like a USB stick. Especially given that this machine has three caddies on board, so it's theoretically possible for me to accidentally mount both backup drives simultaneously! Would I be so silly? it's at least possible. Does anyone know what happens if they both successfully mount? Anecdote time! One of the sites I look after runs a large proprietary application server, and the customer's installed SOE uses a /tmp partition far too small for the installation / upgrade process utilised by said application server. The installer also has this wonderful bug wherein it ignores all attempts to define a new temporary file location. My process for applying hotfixes to the app server includes: Create a large empty file under /var/tmp . Create a filesystem in this file. Mount it over the existing /tmp using the loopback driver. Run the upgrade. Unmount the temporary /tmp . Say you have the first filesystem mounted on /mnt/BACKUP , and some processes have open file handles on that first filesystem. Mounting a second filesystem over /mnt/BACKUP will not interrupt those open file handles - all reading and writing using those handles will still use the first filesystem. I *think* that new file handles opened by those old processes will use the second filesystem (including readdir() calls and the like), but I haven't tested this too thoroughly. New processes attempting to read from /mnt/BACKUP will only see the second filesystem mounted there. Listing the mounted filesystems with the mount command will show two filesystems mounted on /mnt/BACKUP . I have no idea what will happen when you just run umount /mnt/BACKUP, and would suggest being more explicit about which filesystem you want to unmount. Bottom line, though, is that you won't break anything by experimenting with this. If you're nervous, make sure you have a backup of the filesystems you're playing with, or create a couple of loopback ones to test with. Also, I can't wait until the end of this month, when those app servers are retired... -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html
[SLUG] Verbatim keyboard special keys
I have a Verbatim keyboard which is about four years old. It has a special key at the top left which 'shifts' the functions of the function keys to some non-standard program-specific settings; e.g. F2 becomes 'New' and F7 becomes 'Spell Check'. When booting into Linux Mint this option is turned on by default, and it's a bloody nuisance. There is also a row of special 'launching' buttons along the top for programs like Word, which could be useful if I could work out and change what they are actually sending. Can anyone with experience of this come up with a way to prevent the shifted settings starting up by default, and/or a key interceptor program which could at least tell me what codes the 'shifted' function keys are sending to the CPU? Thanks, Jon. -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html

Xev can tell you what's being pressed. I don't know how to reset the keyboard to a known state, though.
