CRASH IN UBUNTU 32 BIT

Mar 27, 2011 LETRA link
Hi, I installed the software from the Ubuntu Store has been updated before the start and immediately I got an error I can not debug console. My computer is a Sony Vaio desktop, with 12 GB of RAM and Nvidia GeForce GT 330M/PCI/SSE2 and Kubuntu with kernel 02.06.1935 10.10-25-generic-pae

Thank you for your help.

Why on earth would you run 32-bit Linux on a machine with 12 GB of RAM? You're likely running into an issue with PAE. Re-install with 64-bit Ubuntu and try again.

The computer's RAM is independent of the system is 32 or 64 bits. The kernel is the generic Ubuntu, I see it is a misconfiguration problem of the computer.

I am not sure if 32 bit linux will actually use more then a few gigs of that....

1. Try Linux 64bits. The last problem was Flash, but it solved with Adobe's 64b version

2. Check your errors.log inside your installation, defaults to ~/.vendetta. Post here the last lines or anything meaninfull.

32-bit Linux can use that much memory, but only with a specific kernel config. Even then there's limitations per process and with MMIO/video RAM/etc.

Either way, VO shouldn't be running out of memory on that machine, so that's not the problem here. You should check your errors.log file and/or try running VO from a terminal to see if any useful messages appear there.

Good luck!

"The computer's RAM is independent of the system is 32 or 64 bits."

You are grossly mal-informed.

A 32-bit OS and/or architecture can generally only access 2^32 bytes of memory (4 GB), though lots of factors can lower this number.

A 64-bit OS and architecture can (in theory) access 2^64 bytes of memory (~17ExaB), though I'm pretty sure no one's tried it yet.

Exception: Pentium class processors on up (Yes, going back to the original Pentium classic) supported a feature called PAE or Physical Address Extension which provided for 36-bit memory addressing on 32-bit machines that allowed up to 64 GB of memory to be used (and was actually accomplished using NUMA (I'll let you Google that one.)). PAE will allow a PAE-supporting OS to address the full amount of memory over 4GB, but any single process (like a running copy of vendetta) can only address a maximum of 3GB, plus there's bugs and inconsistencies in how well PAE is supported.

Your best bet, follow the advice you've been given and install a 64-bit OS.

PAE was added in the Pentium Pro, CR.

There's no reason 32-bit Linux shouldn't run VO on his machine. My laptop has over 4GB of ram and i use 32-bit Linux for application compatibility reasons. VO works fine on that machine. Yes it's a waste of hardware, but it still should run.

At the moment, LETRA hasn't provided any useful information about the error he's getting. Let's not go jumping to conclusions about what's going on without even looking.

LETRA, please paste the error message you were getting on the console. The last few lines of your errors.log file would be useful too.
