After install I get applet removal error prompts

I tried using the 10.04/2.5.0 LiveCD on two different XP systems (I verified the hashcode of the CDROM I made) and I receive error prompts asking if I want to delete some applets:

OAFIID:Gnome_NotificationAreaApplet
OAFIID:Gnome_IndicatorApplet
OAFIID:Gnome_FastUserSwitchApplet
OAFIID:Gnome_Panel_TrashApplet
OAFIID:Gnome_ShowDesktopApplet
OAFIID:Gnome_WorkspaceSwitcherApplet
OAFIID:Gnome_WindowListApplet

I also tried doing an install side-by-side with Windows XP to see if I got different results. Same problem AND there's no boot choice menu - it always boots straight into XP on powerup as if no install was ever performed.

I have a Dell Optiplex 240 with an ATI video card and a Compaq Evo running Windows XP (I used the same video card pulled from the other machine).

Finally, I tried booting from the LiveCd without the ATI card installed, just to see what would happen. Same error messages plus I got a message saying Ubiquity crashed.

Any suggestions? Thanks!

Hi

Try the 8.04 Live CD

Looks like the Optiplex is a P4 machine, so it is probably too old for 10.04, it won't run well with it either.

regards

Yes, both are P4 machines. I'll try the 8.04 LiveCD and see if it works better.

Sounds like I ought to find a newer 'old' machine, so I can use 10.04 in the future.

Thanks for both replies!

Sounds like I ought to find a newer 'old' machine, so I can use 10.04 in the future.

There is no correlation between Ubuntu version number and Linuxcnc version number, nor between it and performance..
Very few new computers run as well with the rtai kernel for 10.04, as some P4s did with the kernel for 8.04.

If you get decent latency with the P4s, I would stick with them.
The below give a bit more depth on the issues involved

Okay. Understood about not needing a newer machine. I'll stick with my Optiplex GX240 running Ubuntu 8.04 with LinuxCNC 2.5. I already returned the Compaq Evo to the used PC shop...

SOFTWARE UPGRADES: I successfully ran the 8.04/2.3 LiveCD without getting any errors. Happy boy! However, I'm not confident I can wade through what's required to upgrade to LinuxCNC 2.5 and then also disable SMI so my ATI Rage (N625) video card doesn't cause latency problems. I'm an electrical engineer with some rusty software experience, but this Linux stuff is entirely new to me. I used to be smart, but this made me rethink that! Yes, I read the page on disabling SMI, but I don't even know where to begin typing, clicking, poking or otherwise molesting the settings to accomplish this. Can I buy a vowel here?

MEMORY UPGRADE: One issue I ought to fix first is that the machine only has 256MB SDRAM at the moment. I found some memory sticks on Amazon for it but haven't bought them yet. Wise move or unnecessary (hardware specs ask for 512MB, so I assume I ought to comply)?

OTHER UPGRADES?: The hardware compatibility/latency chart only said to disable SMI for ATI Rage video cards, so other than adding more memory, is this old Dell Optiplex GX240 good to go?

Thanks in advance for the assistance. I promise not to be a helpless noob for very long...

Peter

John,

Sounds reasonable to upgrade to 2.5 once installed. Yes, I can connect to the internet. I was more worried about the SMI disabling process. I can't yet decipher the instruction page.

Should I wait and install the larger SDRAM before proceeding with the install_8.04/upgrade_to_2.5/disable_SMI process, in order to assure that each step has enough working memory to succeed without errors/crashes? If it's okay with just 256MB SDRAM, then I'll slog ahead this evening and see what happens.

Regards,
Peter
