But then I thought what the heck I'll give 6.4.1 a go first. Tried to install it over the old version so I could keep all my current work. That didn't work. Ended up with 2 different boinc installations side by side somehow. So restarted the old version & aborted & reported all work then deleted everything and reinstalled the new one. Took a bit of stuffing around but I finally got it to work (manager wouldn't connect to client), can't remember how I did it. Think I had to start both manager & client in a terminal to make it work. Not game to shut it down & try again, but we're in the middle of storm season here so I'm sure I'll be forced to restart again sooner or later :-). Anyway to get to the point. It now sees my graphics card & is happily crunching GPUGRID :-D Thanks for your help & patience :-)

Did you somehow tell autostart to start boinc with the /home/rob/BOINC directory as boinc's working directory? Yes What you should probably do is remove boinc from the autostart and run /home/rob/run_client in autostart. The run_client script does a cd to /home/rob/BOINC first before starting the client. Trouble is I am not quite sure how to run run_client in your autostart. Look at run_client's properties. If it's recognized as a shell script then maybe you can just set the excecutable permission and put a link to it in autostart. Or you may have to rename it and add the .sh extension to make Ubuntu recognize it as a shell script. run_client was only a text file. I renamed it to run_client.sh & added it to autostart and removed boinc. No good :-( Boinc doesn't start. Now even though I've changed everything back to how it was before, Kubuntu will only start in command line for some reason???. I'm really starting to think theres something wrong with my install, because it won't shut down normally either, and hasn't since I upgraded to 8.10. It goes to a blank screen then hangs. I have to press the start button on the comp to get it to log out & shut down :-( Another thing I forgot to mention. Having /home/rob/BOINC/boinc in Autostart is the only way I can get boinc client to start. It wont start when I click on Boinc manager, & wont start when I click on the actual boinc file. Which I find strange, because the link in autostart points to that file anyway???

No, did a complete removal in Synaptic to get rid of all traces of the package manager installed version. Then deleted & reinstalled 6.3.21 are you still starting the client by having the OS run the daemon script (/etc/default/boinc-client) at boot time? Nope 3) if not 2) then how are you starting the client? I added /home/rob/BOINC/boinc to System settings>advanced tab>autostart, in the start menu. I don't autostart Boinc manager, because I've found that for some reason version 6.3.21 takes up nearly a whole core of my cpu. So I just start it when I want to check on something & leave it closed the rest of the time.
4) Message boards : Questions and problems : Can't load library libcudart (Message 21388) Posted 19 Nov 2008 by Rob Post: I installed BOINC 6.3.21 on my Kubuntu 8.10 machine a couple of weeks ago so I could run GPU grid. Trouble is when Boinc starts it says in the message tab "can't load library libcudart" & "no coprocessors found" I assume the first message means it can't find or load the libcudart.so file, which I also assume tells Boinc where to look for or how to identify graphics cards? The libcudart.so file is in the Home>BOINC folder where the installer put it, & I've updated nvidia drivers to 177.8 & my card is a 8800GT, so in theory everything should work, but it doesn't :-( I've tried reinstalling a couple of times to no avail & am now at a complete loss??? Anyone have any ideas ?
5) Message boards : BOINC Manager : Negative CPU time Left -0.000000 (Message 21387) Posted 19 Nov 2008 by Rob Post: I get the same message on all my projects on Kubuntu 8.10 with BOINC 6.3.21, although 6.3.21 works fine on my Win XP box.
6) Message boards : Questions and problems : Boinc manager wont attach to boinc client (Message 21234) Posted 14 Nov 2008 by Rob Post: 6.3.x comes with libcudart.so. You may have somehow excluded that file. It needs to be in the same directory as the binaries and the 6.3.x Berkeley installer (what I call the manual installer) will put it in /home/bob/BOINC where it needs to be. It's there where it's supposed to be. Even put a copy in /var/lib/boinc-client/ when I was fiddling earlier to see if that helped. It didn't. I'm running down my cache now and will uninstall everything & start from scratch. Should be within 24 hours. Thanks for your help :-)
7) Message boards : Questions and problems : Boinc manager wont attach to boinc client (Message 21232) Posted 13 Nov 2008 by Rob Post: It works only with nVidia cards that use certain GPUs that are supported by CUDA. Support for ATI cards is planned. My card is 8800GT & is supported. I think it all comes down too having remnants of 2 separate Boinc instalations lying around and some things aren't were they are supposed to be. May have to reinstall again yet :-( Anyway, where are the BOINC binaries placed in Ubuntu? No idea. I think the boinc version installed by the package manager puts them in /etc/bin/ but as for where a manual install places them, your guess is as good as mine, probably better :-) If I uninstall/reinstall again, this time I'll use "mark for complete removal" which I didn't even notice last time so just used mark for removal instead. Then hopefully when I do a manual reinstall everything should be where it's supposed to be.
8) Message boards : Questions and problems : Boinc manager wont attach to boinc client (Message 21229) Posted 13 Nov 2008 by Rob Post: If the manager will not connect to the client automatically when you start the manager then maybe the client is not running? It is running. gkrellm shows 100% cpu usage & I had checked in system monitor just to be sure :-) I started following your latest suggestions but when I got to "Then create a symlink /etc/bin/gui_rpc_auth.cfg" I realized that no /etc/bin folder exists. So I thought to myself, I wonder what would happen if I just copied /home/rob/gui_rpc_auth.cfg to the /var/lib/boinc-client/ folder. It worked :-D. Trouble is I still have my original problem in that it wont recognise my graphics card "no cuda devices found" :-( Anyway thanks for your help. Any suggestions for getting boinc to see my vid card ??? :-)
9) Message boards : Questions and problems : Boinc manager wont attach to boinc client (Message 21214) Posted 13 Nov 2008 by Rob Post: For trouble shooting purposes I thought I'd show error messages that come up at each stage. 6. chmod: cannot operate on dangling symlink `/var/lib/boinc-client/cc_config.xml' chmod: cannot operate on dangling symlink `/var/lib/boinc-client/global_prefs_override.xml' chmod: cannot operate on dangling symlink `/var/lib/boinc-client/gui_rpc_auth.cfg' chmod: cannot operate on dangling symlink `/var/lib/boinc-client/remote_hosts.cfg' 7. ln: creating symbolic link `/home/rob/gui_rpc_auth.cfg': File exists All other lines are accepted without comment.
10) Message boards : Questions and problems : Boinc manager wont attach to boinc client (Message 21211) Posted 13 Nov 2008 by Rob Post: Still no good :-(. The first 4 steps went off without a hitch. I verified it by checking under applications>system>user manager>groups. Although the line "boinc-user:x:<group ID number>:" is actually just "boinc:x:<group ID number>:" on my comp. After that I typed in all the other lines, but boinc manager still remains "disconnected" even after a system restart. On lines 5,6,&7 I had to change boinc to boinc-client, otherwise it said something along the lines of directory not found or directory does not exist. So I was wondering if one of the boinc's in line 8 should also be changed to boinc-client ??
11) Message boards : Questions and problems : Boinc manager wont attach to boinc client (Message 21209) Posted 13 Nov 2008 by Rob Post: I run Kubuntu 8.10 & wanted to try GPUGRID which required me to upgrade to Boinc 6.3.21. I installed it in my home directory, edited /etc/default/boinc-client file in the old install so it pointed to the new client & started it on startup. Also deleted the original boincmgr file in that directory & replaced it with the new one. Everything was fine except it wouldn't recognize my graphics card even after updating the drivers. So I decided to start from scratch & uninstalled the original version with synaptic and deleted the new Boinc folder then reinstalled the new version. Now boinc client runs, but when I start boinc manager it can't attach to the client. After some searching I found a heap of boinc files in /var/lib/boinc.client, which I assume are from the original installation & is where boinc client is starting from. So what I want to know is what do I have to move or edit to get boinc manager to connect to the client again, or am I better off just deleting everything again manually & reinstalling again? Sorry for the long winded post & thanks in advance for any help :-)
