Running in terminal [recovery] mode, because the GUI would just not load, and reverting from something broken in kernel 3.0.0-22 to 3.0.0-20 to even be able to get into terminal, just now ran the sudo apt-get update / upgrade set to see that a linux kernel update was being held back. Blind anyway [in GUI terms], chanced it and ran aptitude [a gem program when normal installs fail] and keyed

sudo aptitude install linux-generic linux-headers-generic linux-image-generic which listed out 3.0.0-23 was ready to install... 49.,8MB download and taking 248MB when unpacked and installed. Short story, for it was really short... installed on the fly, typed sudo shutdown -r 0 for immediate boot, and here we were again, back in a spiffy 3.4 Gnome frontend.

Whilst typing, last weekend, hiding for the sun the makes that perfect horizon to horizon arc without anything inbetween to interrupt it's effect, when outdoors, and sitting in that terminal mode just for the heck typed hibernate. Linux Ubuntu is good... it told me that it was not installed but I could and gave be the sudo apt-get install hibernate. So done, then typed hibernate and it nicely listed out what it would save in memory and used VM and away it went... silence in the room... tired of howling fans. Pushed the power button, getting the little deceptive GRUB many as were there no hibernate to start from, selected the kernel of choice and up it came in a jiffy... hitting ground running... the boinc message log confirming there was no fresh start that preceded to continued crunching.

On to other things now... I promised to cook, pasta ripiena di riccota, my fav. I'm the cook!

Been experimenting with latest Ubuntu final release Quantal 12.10 on a big/fast USB 3.0 stick with persistent set and inserted into the octo laptop [discovering that the VINA jobs race on this system 60-65% faster on Linux (see SN2S forum). Finally found the tool that allows to control the I7-2670QM cycles in form of "indicator-cpufreq" as the CPU was continuously blasting in turbo mode and scary hot to be forced to set BOINC CPU time throttle to 60%. This tool works in Unity and after adding to startup applications and sign-out/in, appears as icon on the top panel. When hit it drops down a list in 0.1Ghz steps from 3.1 to 0.8Ghz and preset options Conservative, Ondemand, Powersave, Performance [indicated on icon with 4 colored bars]. Been running nice and moderate on 2.5Ghz now, stable on client 7.0.36 [which BM menu in this first "use at own risk" build has a mixed up menu]. Punching out about 40K PPD per day... not bad for a former W7 laptop on Linux. ;P

edit: actually pulled the tool from the "ubuntu universe" repository [default not activated]

Good night, and good luck.

I recently found out that the graphics-rendering component of Ubu_v12.10 no longer works with the graphics-hardware built-in to my mainboard. Later, I've read an article stating that AMD did some changes to their graphics driver -- as AMD's response to what I imagine had a considerable impact to AMD graphics users in general and in Ubu_v12.10 in particular. The next-to-the-latest Ubu-version, v12.04, worked well with the former AMD drivers/hardware before the change. Luckily, I have an unused HD-5700 and when I installed that, whalah... I have Ubu12.10 in all its glory where there was once a crippled Ubuntu12.10 UI!

And the good news is, after having started to GPU compute [the low intensity type needing 0.3% CPU cycles] and installing the Bumblebee and Primus display drivers [intended for laptops to extend battery life], the desktop power consumption is down to 160 Watts/Hour, 2 watts better than I had it for W8, which had it down from formerly 170 Watts under W7 to 162 under W8. The surprise was that the difference between 100% CPU load and adding GPU computing, was only 8 watts per the killowatts meter... but this is only a humble GT 220 :D

Low signal or intermittent connection or none at all? At least for me the problems disappeared since 12.04 [mostly] and have a stable on 12.10 Ubuntu, but still issue the sudo iwconfig wlan0 power off command, so the stick does not go to sleep causing BOINC to start crashing tasks [when BOINC is on scheduled connect]. What I have is a D-Link DWA-140's. The router is set up with fixed IP assignment [table linked to the HW MAC code], and DHCP on at client side, which of course will still always fetch the same IP offered by the router.
