Is there any way to set up my system so that, just before I run out of RAM, and SWAP is utilized, I can get a warning message so that I can kill the memory hog before my computer slows to a crawl?I'm a programmer, and it's happened a few times that my programs have memory leaks and run over into SWAP and effectively freeze my system.

It installs fine, but when I run the command the launch the configure gui I get a strange warning message.

Why is it when I run gedit, there are always tonnes of error or warning messages? (Even though my gedit ran successfully)
To name a few:
1. GConf error: failed to contact configuration server; some possible causes are that you ned to enable TCP/IP networking for 0 RBit, or you have stale NFS lockes due to a system crash.
2. Failed to get connection to session: Did not receive a reply among others.
Just to mention again my gedit is running fine though. Is there any configuration that I missed out? or I can disable to avoid these nuisance?
I was trying to install Ubuntu as a dual-boot on my Windows Vista laptop. The hard drive is 250 gb: Vista boot 157 gb partition; a partially-occupied 33 gb partition which was designated as swap-space; a newly partitioned and ext3 formatted 30gb for the Ubuntu installation. I believe there is also a hidden partition ~20 gb with "hidden" system info. During installation I received an error message concerning the swap space partition, which forced me out of the installation and back to the ubuntu partition manager screen. Now in Vista my 33 and 30 gb partitions are missing. Is there anyway I can get back to pre-Ubuntu state?

View 2 Replies View RelatedRecently my F14 x86_64 powered laptop started to present some bad behavior: it can not longer hibernate.
In order to "exercise" the laptop's battery, sometimes I let the machine run until the power goes off, but I learned that Fedora has an elegant solution: it puts the laptop to hibernate. However recently, perhaps after I installed the Catalyst driver (which is working fine BTW), when it tries to hibernate an error message is displayed saying something about "not enough swap".
I read somewhere that in some scenarios swap memory is no longer important for system's performance, that's why I created only a 1.1GB swap partition, which does not match the RAM (3GB) and I wouldn't think it should...
What can I do here in order for the laptop to hibernate again? Is the Catalyst driver the one with a problem, or should I expand the swap space for it to match the installed RAM? A workaround perhaps?

View 5 Replies View RelatedRAM for older machines like I use is fairly cheap these days. But flash memory is just as cheap or cheaper. So I'd like to ask about the feasibility of expanding my system's memory using flash memory. And about whether creating a partition for swap on the flash memory, or whether a swap file on the flash device, is the better way to go.
By flash memory I have in mind mainly USB sticks or what are sometimes called "pen drives." But I do also have CF and SD cards that, with the proper cheap adapter (one of which I already own for adapting CF) could be used to create extra swap space. So, what is the current consensus on the feasibility/advisability of using flash memory for swap? I've read about the limited write cycles of flash being an argument against using it for swap. But recent reading indicates to me that the limited write cycles problem applies mostly to older, smaller-capacity flash memory. Some will come out and say that, for larger-capacity flash memory, the life of the device is likely to exceed the amount of time your current computer will be useful (I think I've seen estimates in the range of 3-4 years life--minimum--for newer, higher-capacity flash memory).
A more persuasive argument I've heard against using flash memory for swap is that access times for these devices can be much slower than SATA, and maybe even IDE, hard drives. That would certainly dictate against using flash memory for swap.
So, how about some input on this issue? Anyone using flash memory for swap? If so, what kind (e.g., usb stick or SD/CF)? Are you using a swap file or a swap partition? How's system performance? Likewise, has anyone had flash-memory-used-as-swap die on them? The consequences would undoubtedly be dire. Also, has anyone measured flash memory access times to confirm or refute claims about slow access times? Are some types of flash memory better/worse than others in terms of access times?
Does one need to Check the Swap filesystem, from time to time
