Wine is one of the coolest things I've ever seen, but unfortunately it's still not enough to suit my needs as version 1.38 can't install any of the .NET libraries.
I'm trying to boot windows 7 on virtual box, but it seems to demand quite a bit of memory. The "recommended" amount is 512MB, and upon checking my kernel only has 488MB total ram with not much room to spare:
I've tried giving the virtual machine memory sizes in the area of 192-256MB, but that's way too much and the system locks up and aborts from it. Memory sizes in the area of 128MB is just too small and it throws an error that there just isn't enough ram to boot. So the only thing I can do to make this work is to increase the size of the ramdisk for my host OS so I can give more to the virtual machine (not to mention things like flash animations are horribly slow and I'd like to see them get more fluid).
I see that I have 16 ramdisks available to me:
Code:
billy@billy-desktop:~$ ls -l /dev/ram*
brw-rw---- 1 root disk 1, 0 2010-02-17 09:54 /dev/ram0
brw-rw---- 1 root disk 1, 1 2010-02-17 09:54 /dev/ram1
brw-rw---- 1 root disk 1, 10 2010-02-17 09:54 /dev/ram10

I looked at some guides here and there, but apparently my setup isn't quite the same. I don't have a menu.lst file in boot/grub, and I don't have a grub.conf file anywhere. So I don't know what file I'm supposed to edit for this.

Here is some article, but somehow GRUB setting takes no effect, size is still limited to 100MB. I need to get ramdisk with size about 700-1500 MB.
Whenever I try to change the sizes of the windows on my screen I get a cursor which is a double arrow. There seems to be only one X- or Y coordinate on the screen where I can pick the side of the window, it seems to be only one pixel wide. This makes it hard to get hold of the side to change the size of the window. Is there a way to enlarge this location to a few pixels so it is easier to point the mouse to the right location?
I set my swap partition a bit high and now want to shrink it down and possibly merge it with one of my other partitions. I don't have dual boot, just have a second partition on the drive for data. Can I merge these easily?
I have reformatted my hard drive with allocation size 64K for a better performance on my WDTV HD media player(dealing with large files). When I mount this drive on Linux, the mount tells me that "blksize=4096".If I keep writing files usinghis default etting(blksize=4096) to my NTFS formatted hard drive, will my WDTV be able to benefit from the performance improvement of 64k allocation size ? Should I try and mount my hard drive with a larger blksize ?I did some research on google but couldn't find an option to increase the blksize when mounting an NTFS pre-formatted drive.
maximising, minimising or simply changing the size of a window takes ages and the whole system appears to freeze for a few seconds. system monitor registers a cpu load spike.
I find that changing the window size is extremely difficult. The area to click and then drag is very tiny and requires very precise arrow positioning. Is there a way to increase this area?
i have changed my monitor from crt to lcd and find the fonts to be a little out of focus,
so far i have achieved native resolution of 1280x1024 in gnome which is great! i have configured grub by adding the vga=xxx appropraite for native resolution of my monitor which is great !.........but herein lay the problem, everything is so small and stuck up in the left corner , so small that i cant read it very well.
how do i increase the font sizes at cmd prompt without changing the resolution ? dare i say ........in windows i would increase the DPI , how do i achieve this in centos ?
I'm having issues changing the canvas size. I'd like to overlay two graphs and hence I wish to extend the canvas and shift one graph up and the other down and perform an overlay. Everytime I attempt to change the canvas size I run into issues with the canvas not being able to extended to twice the height. I am changing the dpi values. Anyone know a smart way of doing this? I am changing through the print setup options.
How do I change the size of the available shared memory on Linux?evidently 4GB is not enough for what I am doing (I need to load a lot of data into shared memory - my machine got 8GB of RAM).
So I set up that OS I was talking about, everything I need, staying away from the "Startx" command, and it's working very very awesomely except for ONE little problem. The console font size is too big for me, and honestly I don't know how to change that. Coming out of Ubuntu, I'm realizing I don't know as much about config files as I think I do :P
Any way I can change the font size? When I use the GParted live cd, I see a line in the start up that mentions changing the frame buffer to 700 x 48 or something, I'll get specifics soon (computer's not on me) and it makes the font and everything just how I like it.
I have a ubuntu linux working in TEXT mode. I would like the change the font size (or if possible, get my terminal with inconsolata font). How can i do it?
My laptop has a 60GB hard drive, which my ex-husband set up with a 20GB partition for Windows XP and a 40GB partition with Suse 11, which suited me fine at the time. However, I'm now finding that I need to install a whole bunch of extra Windows programs relating to my work, and the 20GB partition is no longer sufficient, while I'm hardly using any space at all under Linux.
how I might go about redistributing the space between the two partitions (any other solutions to my lack of space problem also welcome)? Please bear in mind that I'm pretty clueless when it comes to this kind of thing!
have a gzip file ABC_000023232.gzipBCD_023232032.gzipI want to split these files into smaller files but keep the extension same because I am using this as a variable in a script
We have some large files with sampling data in it. Don't want to delete these files. But want to quickly overwrite the file with 0s and/or 1s and preserve the original file size.
I created a ram disk with this command: sudo mount -t tmpfs -o size=2048M,nr_inodes=500k,mode=777 tmpfs /var/cache/apt-build/build When I run apt-build, I got an error message that the disk is full (unable to copy file or something). But no disk was full when I checked with 'df'.
we know the maximum of files created from the nr_inodes number? Or is there any other option that determines the max number of files created?
how could i mount the whole system into the ramdisk?I follow the article "http://www.linuxquestions.org/questions/red-hat-31/building-a-diskless-redhat-enterprise-linux-cluster-765393/",and it works.when i use the "df -h" on the diskless client .I find many system driectory is mountted from image_server.when i stop the connection between img_server and diskless client,the diskless client stop working. my question is how can i mount the whole system into ramdisk.
After some hours of googling, I've managed to increase the size of the default ramdisks (/dev/ram0-16) to 1 GiB each, I raided them together with mdadm to try it out, then created a filesyste, mounted it etc etc. No problems. The problem comes when I used gparted to move my windows partition over and in the unallocated space (1 GiB), I created an unformatted partition (/dev/sda2)Now when I try to create the raid array I get the following:
Code: :~$ sudo mdadm --create /dev/md0 -l 1 -n 2 /dev/ram0 /dev/sda2 mdadm: Cannot open /dev/sda2: Device or resource busy
I'm using some milters on a Sendmail box that recommends using a RAMdisk [tmpfs] to store temporary files, the performance benefits of which are quite noticeable. However, the problem is if a huge number of messages are all delivered at once this partition can be pushed off the physical memory and into swap. When this happens the performance tanks to about 1/20th to 1/30th of normal.Is there anything I can do to keep a tempfs from being swapped to disk?
