I did something wrong while setting up my swapspace so now my main HDD is linux-swap I am dual booting windows and ubuntu, but now I can't boot into windows nor acces the partition because it is swap now.
View 9 RepliesI run a memory-hungry process (mkcromfs) which consumes more memory than I have physical memory on my latop, so it is paging and swappin and thrashing all the time and loadavg is about 2 (compcache is already in use with usual swap partition as well), but slowly moving forward (Although I afraid it will finally try to allocate >2GB and crash draining 2 days of thrashing).
When I want to use the laptop for something else, I stop the process, start X server, firefox and other programs. The problem is that when I start Firefox the loadavg jumps to 10 and the system becomes almost unresponsive at all (long time to turn on/off caps lock, slow mouse cursor position updates, slow switching from X server to Linux console, slow login).
The stopped mkcromfs still holds a lot of memory (464.8 MiB and slowly falling) and moves it to swap only when more memory is needed for some other program, which results in a great slowdown.
How to tell the Linux to swap out this process entirely (e.g. I'm not intending to resume it in short term), possibly waking from swap other data? Also it will be useful to be able to specify the exact swap device to swap the given process out (for example, mkcromfs's memory is useless in ramzswap).
Update: Now I just write a 400-600M of data from /dev/erandom to tmpfs and it makes mkcromfs to shrink. Is there more proper way?

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

View 1 Replies View RelatedI have 2 hard drives, 1 with Windows 7, and one with Ubuntu.
Before installing Ubuntu I had PCLinuxOS then I got a book on learning Linux that is Ubuntu specific so I formatted it and installed Ubuntu 9.
My problem is:
When I boot up I get a WINDOWS bootloader first that lists:
Windows 7
Ubuntu
Then when I click Ubuntu I get the GRUB bootloader.
I've tried reinstalling Grub. I've also tried SuperGrub but none of the options worked, most returned error 15.
So I want ONLY GRUB to show up when booting. From there I think I can edit the grub file to set a timeout of 3-5 seconds, with Windows 7 as DEFAULT boot (Do I need to type "setactive" under my Windows 7 entry to do this part?)

I no longer want or need the windows partition. so I used system > administrator> disk utility to delete the windows partition. Now to hopefully prevent a problem. How do I enlarge the Ubuntu partition without causing problems?
Can I do it while I am ubuntu or do I need to do it from the live cd or what?
Its being a while that I can't download anything from the main server or any server for ubuntu (updates, programs, etc...) I can connect to the internet I can download things from the internet but anything pretending to ubuntu I just can't I've tried everything and it just doesn't work. I have an internet connection and i tried switching servers even clicked select best server and this is the response "No suitable server was found please check your internet connection" I've clicked and unclicked things I just don't know what else to do.
View 2 Replies View RelatedI tried looking all over but all i can find is people using Grub and not answering the question and i dont want to use Grub as the main one. Once the computer starts it going into Grub then i cacn chose between Ubuntu or Windows 7. I want it so i loads the Windows 7 boot loader first then i can chose Ubuntu or Windows 7. After i chose Ubuntu then it loads Grub.Example:I want to do it like it does it with Wubi but dont want to use Wubi

I'm trying to make the Debian sub menu appear by clicking 'on' the Debian box in System -> Preferences -> Main Menu but when I exit the Debian sub menu doesn't appear. One post I found talked about ROOT owning the directories, but not sure if that is the case with me or not.
I last asked this four years ago and got a response with a very lengthy script that had to be run at boot time, in terminal mode.
Actually the sound works when I install ubuntu in virtalbox but if I install ubuntu as a main operating system in my PC the sound didn't work.

I'm trying to set up my system(Ubuntu 10.04hat the main menu and its contents (application, places, system, etc) do not appear(or are hidden in such a way that the user cannot access it). This sounds counter-intuitive. I know. I tried deleting them by hand,but they reappear after every reboot. Is there a system file with preferences that I can edit or something else that can be done?
