Regards,Barry. mutex is short for mutually exclusive, it means that if the lock is set then no other parallel process is allowed to mess with the thing that is being locked. Semaphores are like mutexes but are slightly more sophisticated. http://geekswithblogs.net/shahed/archive/2006/06/09/81268.aspx -- ubuntu-uk@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-uk https://wiki.ubuntu.com/UKTeam/

There's lots of work going on to remove some locking stuff, and that may have been one of them.

[ubuntu-uk] wifi dongle driver .....
Hi there ... I got a wifi dongle from e-bay today. Very cheap. It turns out to be a Realtek RTL8188cu. There was a disk with it which includes a Linux driver that need building. It builds and runs just fine on 10.04 and 10.10, but under Natty, I get the error: implicit declaration of function 'init_MUTEX'. I haven't a clue where this used to be defined, and why it's disappeared. Anyone know if there is a workaround? Yes - before someone tells me - I have got it running with the Windows driver under ndiswrapper, but I'd rather have the native Linux driver. Suggestions anyone?

Nice. Just played "what if?" with the specs on that -- got it to a cool £1,600 easy! :) On 13 May 2011 12:16, Trevor Hyde wrote: > On 13/05/11 10:57, Richard Smith wrote: > >> I am thinking of buying a xenon 14" laptop from pcspecialist, can anyone >> see any major problems with ubuntu on it. >> http://www.pcspecialist.co.uk/notebooks/xenon/ >> >> >> >> Doesn't appear to be be over exotic as far as ubuntu's concerned. > > Nice to see how the price falls away when you dispense with the Windows > options! > > > -- > ubuntu-uk@lists.ubuntu.com > https://lists.ubuntu.com/mailman/listinfo/ubuntu-uk > https://wiki.ubuntu.com/UKTeam/ > -- ubuntu-uk@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-uk https://wiki.ubuntu.com/UKTeam/

Most interesting is from their own tech forum: http://www.pcspecialist.co.uk/forums/showthread.php?3748-Ubuntu-compatible-laptop If you are going to buy it would seem best to get a list of the major components they use and see if any of them have difficulties. Wifi always seems to cause great heartache if it doesn't work OOTB (out of the box). You would also want to know if the video supports 3D Unity.
