Hi all, I'm looking at this as a replacement laptop. http://www.notebookreview.com/default.asp?newsID=6106&review=lenovo+thinkpa… Does anyone have any experience of running Linux on it? Is there support for VT-x in the bios. I am hoping to configure it as Linux with Windows 7 64 running in Virtual Box. Regards Stripes

Modern laptops can't run on your lap because they either have passive cooling in the base through a metal shell (like Macs) or cooling vents (like Thinkpads). They also can't run at high speed when closed (so you can't close the lid after starting a big compile) because the keyboard is used as part of the system cooling. The one you are looking at has an NVidia graphics controller which means it will either be slow or have a binary-only kernel module. I expect that KVM will work as it works on my Thinkpad T61 and I haven't heard reports of regressions in such things. I haven't tried running Windows under KVM though. -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/

Stumped - memory compatibility issue?
by Toby Corkindale 02 Nov '11

02 Nov '11

hey all, I have an issue with some memory that has me stumped. Due to an upgrade, I had 4x1GB sticks of RAM spare, so I figured I'd put these into another machine of mine that currently only has 1 GB total. (It's a little ITX board for media playback) However, after putting the new RAM in, the machine won't boot Ubuntu reliably, and memtest+ on the Ubuntu install disc shows up lots of memory errors. The memory was also *extremely* hot when I removed it from the machine. I tried the memory in pairs of two matched sticks at a time. Returning the memory to original machine, it runs memtest+ with no errors. Is there some kind of memory incompatibility that I'm unaware of going on here? The specs: Machine A, working combination: Motherboard: Intel P35 chipset RAM: 4x 1GB of DDR2-800 Machine B, working combination: Motherboard: Zotac nForce 630i RAM: 2x 512MB of DDR2-667 The latter motherboard says it supports DDR2-800 memory. I moved the CPU over from machine A to B, but that didn't help. I was especially bothered by the RAM getting very hot - I'm pretty sure that's not normal - although that machine is in a very small case without brilliant ventilation. But it was hot after just a few minutes of run time. I wondered if you had any thoughts? Thanks, Toby

jailtime replacement
by Russell Coker 31 Oct '11

31 Oct '11

JailTime.org now redirects to Stacklet.org which requires payment before downloading. There's no way I'm paying $10 to download 143MB of Xen image! Does anyone know of a good free source for Xen images? If not does anyone want to create one? I can provide hosting for Bittorrent... -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/

Some decent speakers for PC's
by Lindsay Sprinter 30 Oct '11

30 Oct '11

For ages now I have been trying to find some speakers that were reasonably priced that were a step above the average offerings found for PC's. Now I will define some terms here. Reasonable price being 3 to 400 dollars. Peformance wise, my main sound system has been in use now since the very early 1980's (I think). The amp is a Pioneer A88X, still a well rspected amp. The speakers being Magnaplanar MG2A's, these are regarded by people that know them is amongst some of the best speakers ever made. The sound being clean and clear, unfortunately these cost something in the order of $1800 in the early 80's something like $6000 to $8000 now. Such level of funds one only wishes to spend once. A few years ago I purchased a 2 speaker Bose PC system this was and advance but was still not good enough. Around 6 months ago I came across a reference to speakers made by a US company called MAudio. A number of points got my interest. First is the company makes professional recording equipment. The second the speakers are fairly large and heavy for powered speakers and use wood (MDF board) cabinets. A number of reports particularly mentioning the AV30 model. I located the dealer in Melbourne and rang them, they said supply was no problem, the price being just under $300, so I picked a pair up. The speakers are of typical powered speaker construction but the size being 220x155x160 (LxWxH). I set them up on one of my systems and tried them out. Initally I was a bit so so on them, but after using them for a number of weeks it became __QUITE__ clear they were a _major_ step up, giving a good clean sound. The reason for my initial reaction is the speakers give a somewhat "brighter" sound than I am used, ie they have somewhat higher treble content. This was cured by dropping the treble control 1 and half db. I was so impressed I decided to get a second set for my development setup. I rang the dealer again to make sure they were availble. They stated that the next model up was on special for slightly under $400 if I wished to consider them. This is the BX5a. These are of similiar construction but are larger (250x175x200) have a kevlar cone on the base speaker (both Bx5a and the AV30 being two way). Also both box's are identcal both having there own electronics. I purchased a set and these were set up in place of the AV30's these being transferred to the development bench. The performance of these give an impression of being better than the AV30's. May mention all of my setups including the Magnaplanars are in differnt rooms so it is impossible for a direct comparison. The BX5a's also can put a __GREAT__ deal of sound without stressing the speakers or in any way butchering the sound. They have some dissadvantages though. The first is the Volumne controls are on the back of the speakers. The second is unlike the AV30's they have no protecting grills on the front. One thing this means is you _______MUST___BE___VERY__________ carefull if laying the speakers down on there fronts unless the surface is dead level as this can put pressure on the dome tweeter. I did have a look at the inside of the AV30's and the construction is quite good. On the whole I am quite happy with both systems, at last getting good sound from my PC's. A last point is as the speakers are designed as monitors for mixing consoles both of them have balanced inputs. the AV30's have both 1/4 inch TRS sockets and RCA sockets. The BX5a's only have the 1/4 inch socket but this will take standard 1/4 inch Tip and Sleeve mono unbalanced plug no problems. The only supplier in Melbourne is StoreDJ, 394 bridge Rd Richmond. Tram route 109 stop 22 is just out side the shop. The only connection i have with the shop is to have purchased the MAudio speakers there! Lindsay

Mono Laser Office Printer Free to good home
by Andrew Greig 30 Oct '11

30 Oct '11

Hi all, I have a Lexmark OptraS 1255 Mono Laser Office grade machine going free to a good home. It has spent its life in a low volume Office environment. I added a genuine Lexmark network card to it and it has been a faithful workhorse. It has been retired for 2 reasons: I have lashed out for the replacement cartridges for our Ricoh colour laser which is now handling all of our domestic load. It is nearly time to replace the cartridge. A high volume (17,600 pages) cartridge can be obtained fro $179.00 here: http://www.cartridgemate.com.au/products/252/lexmark-1382920-black-prebate-… This is not a piece of junk which I am giving away instead of heading to the tip. If you want it I can deliver anywhere from Bayswater to Burwood (where I work), or it can be collected from Bayswater. Send me a message if interested. Andrew Greig

Trouble is everything looks good to me... Apart from the fact nothing is happening. There are some non-kernel processes: init sh -e /proc/self/fd/9 \_ initctl emit startup plymouthd --mode=boot --attach-to-session mountall --daemon The last one seems strange, is this really meant to be a daemon? Seems to be in a select, according to strace. Everything else is either kernel stuff or from console tty2, ie. My debugging console. top says only one process is running, presumably top itself. Any more ideas? Thanks.

ubuntu hang after upgrade natty to oniric
by Brian May 28 Oct '11

28 Oct '11

Hello, When I reboot my computer it hangs with a flashing cursor on a black screen. For ever. However the system hasn't crashed, it just appears to be hanging, e.g. numlock light will toggle. Ctrl+Alt+Delete also works fine. So I reboot it into safe mode, and selected mount filesystems read/write. It does this and then hangs in exactly the same way. So I reboot and enter a command line. I can remount / rewrite and mount everything else fine. I then run "dhclient eth0" and after about 60 seconds I see these messages: [ 88.014507] r8169 0000:02:00.0: eth0: unable to load firmware patch rtl_nic/rtl8168d-2.fw (-2) [ 88.021533] r8169 0000:02:00.0: eth0: link down [ 88.021586] r8169 0000:02:00.0: eth0: link down [ 88.021894] ADDRCONF(NETDEV_UP): eth0: link is not ready [ 90.310097] r8169 0000:02:00.0: eth0: link up [ 90.310433] ADDRCONF(NETDEV_CHANGE): eth0: link becomes ready The firmware exists in the required location: brian@aquitard:~$ ls -l /lib/firmware/rtl_nic/rtl8168d-2.fw -rw-r--r-- 1 root root 1324 2011-08-23 23:23 /lib/firmware/rtl_nic/rtl8168d-2.fw It is possible when mounting filesystems I missed an important step that is required to load the firmware properly (maybe the step that causes the hangs?). However at this point, with the network up, I can continue booting fine. Any ideas? How can I find out what is causing the hang? Is there anyway of creating another virtual console within recovery mode? Thanks -- Brian May <brian(a)microcomaustralia.com.au>
