I login as my normal self from the login screen and RH just hangs on an - empty blue screen. What's wrong? - -A. You have some wrong permissions. I'm guessing you can probably log in as root - but not as your normal user. Basically you need to set the right - permissions with a rule. Setting the correct permissions to null and urandom - allowed me to login as myself and not at root. - - While you are there you might want to set the permissions to ptmx as well - or you may have trouble getting a bash prompt in an xterm. Also refer to the - next question. - -Q. I'm having trouble getting a bash prompt from my xterm. i.e. I bring up a - terminal and all I have is a blank screen with a blinking cursor. - -A. First make sure you have the correct permissions set for ptmx. See above - Q&A for help on this. But I'm guessing that something is wrong with your - /dev/pts, thanks Captain Obvious, heh:) You probably have devpts mounted - to /dev/pts from /etc/fstab. I'm also guessing that you have sysfs mounted - to /sys from /etc/fstab as well. If this is the case then the line in - /etc/rc.sysinit - - action $"Mounting local filesystems:" mount -a -t nonfs,smbfs,ncpfs -O no_netdev - - will have mounted these for you. As a result you placed your call to - start_udev directly after this because the HOWTO-udev_for_dev document - told you to insert start_udev after /proc and /sys have been mounted. - Well start_udev actually overwrites /dev thus anything you had mounted in - /dev prior to start_udev being called will be blown away. So basically, - you mounted devpts to /dev/pts because everything in /etc/fstab was mounted - and then it was blown away by calling start_udev. A simple fix is to remove - the mount devpts line from /etc/fstab and mount it after calling start_udev. - I did the following: - - action $"Mounting local filesystems:" mount -a -t nonfs,smbfs,ncpfs -O no_netdev - /etc/rc.d/start_udev - action $"Mounting devpts: " mount -t devpts none /dev/pts - - After doing so I rebooted and was able to get my prompt from my xterm. - -Q. I'm getting some error messages during boot. How do I get rid of them? - -A. For me it was a matter of setting up Symlinks. Basically, some /dev entries - were being looked for and not being found so an error was thrown. For example, - /dev/cdrom was needed but udev had named it /dev/hdc by default. Basically I - edited my /etc/udev/udev.rules file to create a symlink from /dev/cdrom to - /dev/hdc and my error went away. - -These are some of the things I ran into. NOTE: I hosed my machine more than once -trying to figure this out and a rescue disk was my best friend. If you have any -other experiences and would like to add to this Q&A list feel free to send me a -patch (ogasawara@osdl.org). Hopefully this helped someone. Thanks. -- cgit v1.2.3-54-g00ecf
