After a month of hiatus, a few more niceties:
----------------------------------------Is your boinc core client or boincmgr not running? For Ubuntu, in a terminal (mine is clicompanion), navigate to /usr/bin where the client apps are stored and type in ldd boinc ldd boincmgr this will print a list of libraries. If you see "not found" behind one or the other lib, you're closer to fixing the problem. And yesterday went to read allot about remote controlling the Linux quad from Windows and eventually decided on using the default Ubuntu remote desktop and some VNC server/client components and install the free "ThightVNC" on the Windows 7 machine. Set up some passwords, forced to be asked for a sign in password, the one used for logging into the user when physically at the machine and Wii... at 270Mb 802.11N speed got the Ubuntu desktop on my W7 screen... no more running around the house and configured to only permit internal IP addresses, though it can be set to also accept connection from the other side of the planet. Leaving any machine without a Screensaver password... not on my planet... after the normal 5 minutes idle the VNC viewer session reverts to show the Ubuntu desktop screensaver sign-on screen ... Can't trust those Woocky leakers. :D PS, if you stick to Meerkat for the next 18 months it will automatically morph to the next LTS (Long Term Support) version of Ubuntu... seems to be the way the development paths work at Canonical. PPS, and a screenshot of the remote desktop... the resolution is astounding... note the BOINCtasks icon, bottom left, launching in WINE and the pirateflag waving on me island... no idea who painted this, but liked it from the 1st second I saw this image popping up on the intertube... heck, it's 22 Celsius outside this moment per the SS... time for a walkabout ttyl

Those OS X look-alikes and transparencies does look nice, but how much do they slow down your system? When I enabled Ubuntu's graphical effects, videos in internet television weren't smooth anymore. I mean, H.264 full screen scaling from the resolution of 640x360 shouldn't be a problem for a decent GPU.  Yeah Macbuntu hosed my netbook. Upgraded to Maverick and had video driver problems again. Fixed some of those, then installed Macbuntu. Ubuntu would not load at all after that, the Macbuntu uninstall script failed, so rather than reinstalling Ubuntu I decided to scrap it. Now I'm running Jolicloud. Highly recommend it for netbooks; very lightweight and incredibly easy. Ran an installation file within windows (similar to Wubi) and it installed Jolicloud on my C:\ drive (no repartitioning; can also install solely as Jolicloud w/o Windows). Jolicloud is a modified version of Ubuntu netbook, but works out of the box for most netbooks. Unlike Ubuntu, it picked up my video card driver and wireless right away; took <20 minutes to install. Programs are installed as Apps, similar to iPad/iPhone. (You can also install programs outside of their App Center if you wish). http://www.jolicloud.com/  |

** Though I tried every way possible to build GatoTray util http://gatopeichs.pbworks.com/ version 1.6, but cant get it to complete the compile. The would be icon to show on the panel bar:  and how it would look on mouse hover:  Simple steps in the terminal: ./configure (this one does nothing and gives bash: ./configure: No such file or directory) *** sudo make sudo make install There is a makefile at second step but it seems to not be putting it into the usr/local/bin. Sadly, because this was my original choice of an extremely licked and integrated temp monitor for CPU/GPU/HD for the start bar. GKrellM is way to bulky and CPU cycle using for my liking. *** Search on google found this http://www.linuxquestions.org/questions/linux...permission-denied-107075/ but did not make me any the wiser... not even a denied. Anyone can tell me what I'm doing wrong (probably everything). Did you ever get this working? I see there is a new version. If you try to install it make sure you have these libraries installed--> libgtk2.0-dev I got it partially working, but I still get these errors when I fire it up: gatotray: Can't open /proc/acpi/thermal_zone/THxx/temperature: No such file or directory The icon shows on the bar but there is no temp info as you can see here. |

Hello Sekerob,
----------------------------------------I just installed Ubuntu 10.10 on my laptop and I would like to ask you how did you make to appear on the panel the icons # 4, 5 and 6. See the link to the post I am referring to: http://www.worldcommunitygrid.org/forums/wcg/...ad,28931_offset,40#290282 I have been trying to install HSM and the instructions I found are sending me back to IM sensors and then some tweaking to do, and I didn't quite understand if these IM sensors are the ones you can find in the software centre or not. Which IM sensors package did you use?Where did you find it? Could you please post a guide very basic for a linux newbie like me? (starting from how to install a package which is not in the software centre!)  And last but very important, is there anything like Tthrottle for Linux? Sorry for the many - maybe naive - questions. Thanks a lot. L. [Edit 1 times, last edit by Former Member at Dec 13, 2010 5:50:20 AM] |

@brinktastee,
----------------------------------------Yes, got it to work same as would you found, those missing gtk libs and no the temp remained at zero read out. @latakia, Installed Lm-sensors, and Gnome Sensors applet, then from the "add to panel" Hardware Sensors Monitor and toyed with the preferences (rightclick) to get those I wanted to show, such as only 1 core of the CPU. Names in Synaptic of pieces that are installed: lm-sensors libsensors4 fancontrol sensors-applet Used KrellM for a while but was taking to many cycles imho. Something not in the software centre is first finding a ppa that offers the package, then add it to the Software Sources/repositories... do a trust check, such as is it known in Launchpad? No TThrottle equivalent. For a while played with fancontrol and scripts to make it change the fans speed, and also found a few weeks ago something that allowed to change the number of cycles for a BOINC process (may have written about this in this thread or elsewhere in the CEP2 forum, which does not work very well since CEP2 creates 16 new child processes during a task. There's piles of stuff for Linux, but beyond a glossy front, you really need command line proficiency and scripting skill... and only just starting myself. --//--

Today, after spending hours going around hundreds of trees to shake off the pack of snow before they'd croak under the weight... 5C above zero is not good to get light fluffy stuff, when it comes down for nearly 48 hours non stop... and spend a little time in LaLaLinux root terminal land after downloading the latest 'fixed' NVIDIA driver 260.19.29 and building it up.
----------------------------------------- stop X server: "/etc/init.d/gdm stop" (since control-alt-backspace did not do the job) - navigate to home directory where the file was stored as in /home/myhome - sh whateverthename.260.19.29.run - follow the instructions, to include ignoring a script fail warning - watch proceedings - start X server: "/etc/init.d/gdm start" (which popped the GUI login screen back up) and away we go, that one irritating bug of frequently hanging apps for up to one minute whilst running with OpenGL actually gone. Kernel 2.6.32.27... sticking with Lucid Lynx LTS. PS, whilst it was coming down almost non stop, the hardtop roads were melted free in no time. edit: Bonus, for who came on board [too] late:

I had to remove the old Nvidia driver first to make this work. Tried to install it without removing it and xserver would just crash.
 "System-->Administration-->Additional Drivers-->Deactivate the Nvidia driver. |

'Was tired of the system fan cycling back and forth between idle and elevated, so went on a new search and found pwmconfig, a script driven utility that allows to discover the settings needed at different revs and then apply them, so now I've set them to below ''irritating'' minimum revs of 2100 for the CPU fan. Prerequisites, lm sensors and other bits I'd already installed many moons ago so as to be able to see the fan speed in the panel bar. Trial and error, here's https://wiki.archlinux.org/index.php/Fan_Speed_Control, the end product ''almost'' a Speedfan like control, albeit, no GUI.
And do follow the instructions from the top, which to add includes suspending BOINC during the discovery and config efforts! The program will plot out the settings from maximum fanspeed all the way down to zero, which if continuing to crunch risks to fry you CPU. -- SekeRob |

Maverick 10.10 kernel 2.6.35.25 proofs providing a more stable/performant Ubuntu platform. Still not figured out the ''why'', but now start the fancontrol service after, not before sign-in, nicely and very steady keeps the airscoopers at 2450 RPM, 54C just under the audio awareness level rather than constantly going up and down between 1600 and 2600.
Saturday also reintegrated the kernel file-handling tweaks of Lennarts http://www.webupd8.org/2010/11/alternative-to-200-lines-kernel-patch.html. The CEP2 jobs are on average having a good 5 minutes less gap time... last completed with just 20 minutes slip on a 10.5 hour CPU task, so that's progress. Following an interview this Linus Torvalds, http://www.omgubuntu.co.uk/2011/01/our-exclus...h-linus-torvalds-lca2011/ and other prior file handling optimizations which are going to be in kernel 2.6.37/38, kind of expecting more improvement. We'll see what that brings when the next release after Natty Nharwal 11.04 picks those up. Till now, after much trial and error on the WiFi, and yes BOINC crashing tasks still with 6.10.58 when internet is not reachable, finally figured out that the DHCP, manual DNS setting, but leaving the IP assignment up to the router made the 802.11G fly... even 802.11N runs, but it refuses to go above 54Mb. Somewhere on the hill there a router that keeps trying to connect to my box tearing down the signal quality... and keep your cellphone out of the signal path... makes a difference for some reason at the 2.4Ghz bandwidth. The connection seems to be able to auto-reconnect on fail without running the cron job that does the restart network-manager that I had running under Lucid. --//-- |
