    RE: stable Linux. Truth or Myth?
    I've very rarely had problems with Ubuntu. But on the two or three times I have, it's almost always been the result of a dodgy update (usually drivers) or hardware. These days I only install the mandatory security updates and leave all the optional ones unless they address a specific problem I have. Also, if I want to evaluate a new app, I generally install it into a VM before I put it on the host OS to try it out for stability and impact; learned THAT the hard way! There are a few machines knocking around at my place that haven't been reinstalled in +/- three years and haven't given a day's trouble (even when they've been messed about by Windows apps running under WINE). If I get a reproducible crash situation I tend to start with hardware or something I'VE done rather than a problem in the OS. This isn't me banging the Linux drum but I reckon you'd have to go a long way to find something more stable.

    RE: Ubuntu, 11.04 (fully updated)
    Mint seems to be working satisfactorily but, when I next install, I'll probably go for KDE installation. I've been meaning to cut over for ages but you know how it is (putting things like that off). I'm just a bit too busy at the moment to go through all the pain of getting all my tools and what-nots to work again. Thanks for all the assistance though.

    Sure, I'll give it a go. Just liked the old faithful Gnome IF.

    RE: Ubuntu, 11.04 (fully updated)
    Upgraded to 11.10 and instantly regretted it. The new interface (Called 'Unity' allegedly - which could prove to be the biggest oxymoron of the year) is obviously designed with mobile phone users in mind. To cut a long story short, I scraped the drive and installed Linux Mint. Everything's running perfectly again. Shame about Ubuntu though. Used it since it first came out; loved it to bits as desktop platform for development but, sadly, it seems to have gone for eye-candy in preference to functionality.

    RE: Ubuntu, 11.04 (fully updated)
    Hi again, I must confess I didn't check the MD5 and I seem to have lost the disk I cut the ISO to. That said, I'd be surprised if it was a corruption of the installation as it worked perfectly for about 2 months without a problem. Still, I've seen weirder things so it's certainly possible. I've got a bit too much work on at the moment but, when I've got a spare hour or two, I'll scrape the box and re-install it. If that doesn't rectify it, I'll swap out the RAM, motherboard etc. until the issue is resolved. All that aside, I'm starting to suspect it's something to do with the sound module or driver. I use Banshee and I noticed the other day that the latter is a bit erratic (spontaneously exits with no error condition on a fairly regular basis). So it may be a prob with the sound hardware or driver. I'll keep plugging away though. TTFN.

    RE: Ubuntu, 11.04 (fully updated)
    Hi, Apologies for the delay in replying. The site outage precluded any reply. Yes, I've checked the RAM and it's (allegedly) fine. The problem is fairly sporadic but always seems to happen around 13:00 which, in South Africa, usually means it's pretty hot. However, I've checked the CPU and board temperature and, if the values reported are correct, they're well within the operating limits. I doubt if it's running out of memory, the unit has 16GB on board on I don't think its ever gone higher than 10GB in use even when I'm running 2 or 3 VMs. It may be hardware but, if so, it's a weird problem. The only thing I can think of is that the board or one of the RAM chips has a microscopic crack which opens up when the system warms up. What is VERY odd is that, when it hangs, the mouse just stops moving and whatever was on the screen just prior to the crash remains there. I even tried to ssh into the unit after it had crashed to see if there was still any life behind the frozen display. Nothin'! I think I'll just unplug everything inside and out and stick it back in again. Might just be a loose SATA cable or an intermittent short somewhere. The reason I reported it is because I've NEVER seen a Linux installation do anything like this. Although I've had crashes in the past they've usually been picked up by the kernel and reported. Never had a straight 'freeze' like this. But thanks anyway.

    Ubuntu, 11.04 (fully updated)
    My main PC seem to have caught galloping bit-rot. It's been working perfectly for two months but, in the last week or so it's started spontaneously hanging. I was just filing some emails in gmail (via Chrome browser - v13.0.782.218) and the whole system just hung; not even mouse movement. I haven't added any hardware recently. the hardware is only a couple of months old and I'm not running anything particularly weird except (maybe) VirtualBox (non OSE version). There's nothing I can see in the logs (kern.log and syslog - excerpts below) and I can't find anything on the Ubuntu bug list which might affect me.

    Evolution Mail
    Why is it that mail clients seem to be the only blemish on the otherwise perfect skin of the Linux desktop? I've tried Thunderbird; not a wonderful experience. Was recommended to Evolution which I've now used for several years despite its tendency to crash spontaneously, corrupt your emails or refuse to delete anything from trash. I've finally had enough. 1) Does anyone know a way to extract mail data directly from the Evolution databases to allow me to, at least, [b]LOOK[/b] at my old emails (despite Evolution generating segmentation violations and crashing on load)? 2) Is there a recovery tool for the email database I could use to try to reconstruct the evolution mail data? 3) Is there a stable email client (no bells and whistles) available which doesn't fall apart like a hooker's dressing gown? Or do I have to bite the bullet and write one (which would [b][i]really[/i][/b] p**s me off. :angry:) [img size=633]http://www.linux.com/media/kunena/attachments/legacy/images/evolutionsegmentfault.png[/img]
