2 questions: Dual monitors and partition permissions
First off, is there any way to get ubuntu to recognize two monitors simultaneously?
Second, I got my dual boot up and running, and have a "shared" fat32 partition that, being 900 gigs, is going to be what I'm running the majority of files and applications from. Problem is... when I'm on linux, the partition is restricted. It just means that I have to go try to open it and then type my password again, but if something's supposed to run from it from boot, it won't work until I've unlocked it. I tried to change the permissions, but even though it lists me as the owner, it claims I don't have the right permissions to do so. |
I've never run dual monitors, so I can't advise.
Wrt your FAT32 partition, your ownership and permissions will depend on who mounted it and how. FAT32 doesn't know about about *nix style permissions, so all files and directories will have the same owner and permissions. You might have to fill me in some on exactly what you want (if I don't guess right!) but I am guessing that you might want to automatically mount this partition when Linux boots. If so, and if you want all users to be able to read, write and execute, add (or modify if a line already exists) the following line to /etc/fstab. Code:
/dev/hda5 /mnt/fat32 vfat umask=0 0 0 The only way I know to change ownership or permissions on FAT32 after it has been mounted is to unmount it and then mount it again. Even the remount option for the mount comand doesn't seem to work. FYI, I have no experience with it, but I've been reading that Linux can now handle reading and writing an NTFS partition. Some are recommending it instead of using FAT32. You can google for more info. |
Uh oh, this isn't good. It's now claiming that I don't have the right permissions to save fstab.

Code:
sudo cp -pvf --backup=numbered /etc/fstab /etc/fstab Alternatively you can copy /etc/fstab to your home directory and edit it w/o priviledge and then: Code:
sudo install -m 644 --backup=numbered fstab /etc |
Okay, that (Sudo installing it after modifying a copy in my home directory) worked. As a note for anyone else trying this, though, I had to include the UUID of the drive as well (if that should have been obvious from what you already explained, my bad).
Thanks a ton, sir! |
Dual monitors? Sure, no problem. I've got Kubuntu running with 3 monitors on 2 video cards at work. It's just a matter of turning on Xinerama support and adding the appropriate lines in your xorg.conf file. Of course, the details will depend on your setup, so you'll have to tell us more about that. However, if you happen to be using a dual-head Nvidia card, the Nvidia configuration tool will actually do most of the work for you.

EDIT: Feel free to obfuscate the UUID if you wish. I.e. replace some of the charecters with Xs. |

# /dev/sda4 UUID=XXXX-XXXX /media/NIFLHEIM vfat umask=0 0 0 Oddly, I seem to be having trouble doing the same with another drive I recently cannibalized from another computer and repartitioned with a GParted live CD. Any idea why this might be? |

If you want to do the configuration by hand, you just need to add a devince, monitor, and screen section for each display and turn on Xinerama. Here's the relevant portions of my xorg.conf file, for reference. Obviously the particular values will be different for your hardware. Code:
Section "ServerLayout" |

Can you mount the new partition manually? |

mount /dev/sda5 /mnt/temp I get a message only root can do that. Is that the message you are getting or some other? If that is the message, try it using sudo. If none of that works, look through /var/log/syslog file for boot time messages involving the disk. (The grep command might be useful for this.) For example, I see messages like: Code:
Apr 10 22:49:35 ratel kernel: [17179574.416000] sda: sda1 sda2 sda3 < sda5 sda6 sda7 sda8 sda9 sda10 > If not try: Code:
sudo fdisk /dev/<name of drive> |
Okay. I got it to mount, but I can't get it into fstab without it cutting off my permissions. If I add an fstab entry for it, I lose permission to mount, it seems. Any idea how to get it to mount on boot?
|
Also: I feel dumb for this, but I can't seem to get to the nvidia config tool, and I'm starting to think I don't actually know what you mean by it.

First, am I correct that this is a FAT filesystem? Are you using a line in fstab similar to what you posted in post #8? If not, please post what you are using. Also, please post the results of: Code:
ls -ld <mount point> |
