Ubuntu login problem
by steve-ALUG＠hst.me.uk 08 Aug '10

(I've been having problems posting to the list - apologies if this appears multiple times!) Hi! Can anyone help? I've got Ubuntu 10.04 LTS - the Lucid Lynx installed, and I rebooted it today, because it seemed a bit sluggish, bit sluggish, and ever since I've had problems logging in and/or authenticating. The only thinks I recall changing are there were a few updates downloaded, and I'd tweaked my Samba config file (smb.conf) and also been playing with the nvidia driver settings, enabling it and disabling it. This machine's a server, and it controls it's own logins, i.e. it doesn't authorise them somewhere else. When I reboot it, I see the greeter, I type in my password, and then it sits there for ages - at least a minute, before I see the logged in desktop. I can try switching to a virtual console (alt-f1 etc) and logging in there, and it takes ages and usually times out (timeout after 60 seconds message). It also happens if I try to ssh into the machine. Once the machine has been up for a while, the login response on a virtual terminal seems to be better, but I also get the problem using SUDO. I also get the problem logging in to Thunderbird on this machine, which uses IMAP to get the mail of this machine, and uses PAM to authenticate. I've looked in the logs and can't see anything obviously wrong. ISTM that this is a problem with PAM authentication, but I've not changed anything, nor do I know what to do about it or what to change. I've installed Bootchart, but there's nothing obviously wrong with that. Any ideas? Regards Steve

Martin Thanks for that. Excellent. I found the option in the BIOS and it has sorted it.

I think it can be turned off in the BIOS. Many kernels ago there may have even been a driver in the kernel for this.

Bubba2 server

Has anyone any experience with one of these? We have just bought one out of some grant funding at a small charity, and so far have done no more than unpack it. It is about the size of a thick mass market paperback, very solidly made. Its running Debian, Etch apparently, and the main reason we bought it rather than build our own, one is very very low power consumption, and two, it comes totally set up with web server, NAS, picture gallery app and so on. The suppliers intend for you to use it as a firewall/router in addition, but we will be using it strictly as a server. Power consumption is minimal, its meant to be a plug in and forget package. Came with a 500G hard drive. We could have got a bigger disk, but it seemed like it would probably be smarter to have an external usb for the extra storage and greater redundancy. Ours is the non-wireless version, you can get them with wireless also. Price 240 Euro. Peter

a deeply puzzling overheating
by Peter Alcibiades 07 Aug '10

07 Aug '10

Any ideas on this? Its a socket 754 machine, something like a 2Ghz Athlon, 1G memory. Debian Squeeze. It has always worked just fine, and in almost all ways except this still does. What has just now started happening however is that the owner has started to read the papers online. Sometimes, it doesn't seem to matter which paper or which browser, there will be a page with 'the wrong kind' of graphics. Its not clear exactly what the wrong kind is, some are fine, others seem not to be. Gradually, the fan will start to speed up. If you now start up gkrell, you can see that cpu temperature starts to rise quite rapidly to the high 50s, and the fan gets very loud indeed. I don't know how far it would go, because one of us closes the browser fairly soon when this happens, and eventually the temperature falls to below 50. It does not do it when displaying pictures. For instance, one can load in a file of a few hundred, and it will display the thumbnails fine, and then one can page through them repeatedly, they come up an display quite fast, and there's no problem. It does do it when rendering some pdfs. Particularly, it did it with a graphics intensive pdf of some sort. I thought about getting a better cpu cooler, this is the stock one, but there is very little space in these smallish cases. And I can't see why this should be happening. I have other barebones of this sort, Asus, and it never does. Another machine is an old 754, and it does not happen on it. I'm not completely sure if this is new, because I'm not sure whether this sort of graphic content was displayed previously. Meanwhile, there's a Novatech small form factor i3 machine at 400 which is looking more and more attractive.... Bought one for someone else, they are fairly compact, quite quiet, and run very cool. 754 is pretty old hat nowadays, so maybe its time. Peter

Strangely, it didn't. I also tried reformatting it, and it ignored the partition. I think it's because the partition has a different drive address. -- Tony Anson www.girolle.co.uk/

enable display compositing in lxde
by Simon Royal 06 Aug '10

06 Aug '10

Hi I have been having some bizarre graphical glitches in Linux Mint LXDE and so far haven't been able to find anyone else with the same problems nor a fix for it. Until now. 'the minimise/maximise/close window icons appear in random places all over the screen when I roll over them. When I move a window over them they dissapear (as if i was erasing them)' I have this exact problem. He appears to be using Xubuntu - I too had the same problem in Xubuntu last night. Oddly enough it didn't do this in Ubuntu. Anyway, he fixed it by 'enabling display compositing' under xfce 4 settings manager. Great, but I am using the LXDE version of Linux Mint and cant find this anywhere. Can anyone offer help or an alternative way of enabling display compositing?

Mint Is Working... Few Graphical Glitches
by Simon Royal 06 Aug '10

06 Aug '10

Hi Well, I found a work around. It seems xorg.conf was configured for the machine Mint was installed on. Moving the hard drive confused Mint as it didnt detect the new drivers/graphics. Luckily I found someone else who has Xubuntu installed on their 240X and they posted their xorg.conf online. So I nanoed in safe boot and replaced the contents of mine with theirs. This worked and I am not booted into Linux Mint LXDE on my ThinkPad 240X. It has a few graphical issues where it doesnt redraw things properly, like it hangs onto window buttons and prints them all over the screen. But I am sure this is a problem I can get round. Anyone have any ideas what this is and how to stop it. It is quite hard to describe. When you open up a window that has the close/maximise/minimise options sometimes these are repeated lots of times all over the screen. Fingers crossed I can get this sorted. After the long haul of getting this machine to dual boot I am just about there at having a fully working set up.

Mint Problems
by Simon Royal 06 Aug '10

06 Aug '10

Hi I tried installing Linux Mint LXDE on my ThinkPads hard drive via a different laptop. This seemed the easiest way. It went ok and grub works fine. Back in my ThinkPad XP still works fine. Mint boots but then gets stuck. It sits on a black screen with some white text saying: Exporting directories for NFS daemon. Starting NFS kernel daemon. Starting NTP server ntpd. Starting common unix printing system cupsd. This stays on the screen. Every 20 seconds the whole screen goes black then the writing comes back. It doesnt get any further than this. If I do recovery mode then it will boot to a linux prompt. Any ideas? I am assuming this is something hardware related. Something to do with it being set up for the other machine. Is there a way of getting it to redetect hardware? Simon -- http://twitter.com/SimonRoyal - http://tinyurl.com/macspectrum. (Sent using Sony Ericsson P990i).
