After a regrettable typo, I reset all the permissions in my filesystem. What is the easiest way to restore my permissions to how they were? Is there a list where i can find the recommended permission settings for each directory?
View 7 RepliesI am on 10.4 with a Dell Notebook (E6400). I use it mostly with a USB mouse. Everything worked fine for about 2 months. Then I shutdown, unplugged the mouse, restarted without the mouse, and my trackpad is broken. It works a little, but text fields and some apps capture the mouse events and won't let go. For instance, the cursor gets stuck in a text field and there is no way (keyboard or mouse) to get out.
I've tried several times to fix this and I cannot. If I boot from a LiveCD then everything works fine. My theory is that the mouse configuration files somehow got corrupted in my plugging/unplugging of the external mouse. How can I reset the mouse to factory defaults? Are there a set of files I can copy over from the live CD?I tried to delete and recreate my xorg.conf file and this did not work either.
I installed the nvidia driver from the vendors homepage. But since it does not support regulation of brightness (and the display is that bright that I want to downlevel it), I wanted to go back to the default display driver which is the nouveau driver.So I uninstalled the nvidia driver and then I realized that I didn't make any backup of the xorg.conf file prior installing the nvidia driver. Shame on me, yeah.Now when the x-server started, it couldn't find the nvidia driver. Okay, fair as it was removed. Next to that my keyboard becomes unresponsive. That's really aching as I can not switch to a text-based console any longer.I'm able to boot into initmode 3 by editing the kernel parameters in the boatloader. I'm also able to edit the xorg.conf with vi in the shell then and start the xserver to test things by calling xinit.
I already tried to recover a bit from this situation by removing the references to the nvidia driver and replaced it with some information I could find on the nouveau homepage - but no luck so far, keyboard still freezes and login window does not appear. I could take a look into the xorg.0.log which warns me about the keyboard getting disabled but I do not really understand why. Next to that I find some other additional information. My computer experience is quite okay, but I'm somehow new to Fedora, I started half a year ago with Fedora 13 on my other laptop which worked like a breeze.
I wondered where I can find information about how to configure the xserver in the default configuration, if there is some reset functionality or so, that brings me back to installation defaults. Those worked ok for the nouveau driver. Unfourtionatly I was not able to gather the correct package name that would probably had helpded me by removing and installing it again.Next to fixing my setup, I had another idea as this is a quite new install to just re-run the install again on to that machine. Is this possible with keeping the files in my homedir?

View 2 Replies View RelatedI was curious if anyone has addressed this issue before. I have set the permissions to /var/log/Xorg.0.log as follows:

-rw-r----- 1 root root 00000 Jan 00 00:00 /var/log/Xorg.0.log
I have done a lsof and the file is being opened by root. I have set Roots umask to 0077, yet after a reboot

I have a Centos 5.3 desktop that I have a development board connected via a serial connection to. The permissions on /dev/ttyS0 are currently set
crw--w---- 1 root root 4, 64 Nov 4 13:56 ttyS0
I have changed them so that they read
crw-rw---- 1 root uucp 4, 64 Nov 4 13:56 ttyS0
But every time I initialize the dev board the permissions switch back to the original state. I have found lots about preventing the permissions switching back upon reboot but that doesn't appear to be the problem.
I have hauppauge pvr-350 which has an mpeg2 decoder with an RGB and s-video out to let me send video to my tv. I'm using the ivtv drivers which work well. To test the card I ran
Code:
cat test.mpeg > /dev/video16
-bash: /dev/video16: Permission denied
So then I did
Code:
ls -l /dev/video16
crw-rw---- 1 root video 81, 5 2010-10-22 12:21 /dev/video16
sudo chmod a+rw /dev/video16
[sudo] password for patrick:
cat test.mpeg > /dev/video16
However the permissions get reset everytime I reboot. Is there any way to pass an argument to the ivtv driver to change the default permissions?

View 3 Replies View RelatedIs it possible "reset" all (X, GDM related) permissions/settings of one user? What would cause one specific user not to be able to log into anything via gdm/the login screen? After providing the proper password, the screen goes black and then jumps back to the login screen. No session alternative works, not even xterm or gnome failsafe. I can however log in via the console (Ctrl+Alt+F6, recovery etc). With another user I can log in via GDM just fine, and deleting and re-adding the "broken" user doesn't make any difference.
Some (maybe) relevent logs:

I'm unable to reset using either the reset option in gnome shell or the command using a terminal. When I select it the shell exits and displays the graphic "exploding" and then it just sits there. Shutdown works fine; just no reset. Any ideas? I've installed from the DVD. I booted the live CD and it resets just fine so I know it's no my hardware

I downloaded the ubuntu-10.04-rc-desktop-i386.iso file and burned it to a CD - i.e. what I thought would be a standard Ubuntu Live CD experience. Imagine my surprise when:On a black screen, there was a new (small) window on the left and a (small) meaningless stick figure on the right at the bottom of the screen, and after a while I got the error window entitled:
Installation failed
The installer encountered an unrecoverable error.

investigate the problem or try installing again.
Since when is installation (with no user interaction) a default when using a (Live)CD ISO image of any Ubuntu RC or otherwise?My only purpose was to boot up into the Live CD environment - but that was not only not presented as an option (normally there is a 30 second countdown) and the usual default is to boot up into the Live CD environment.This was not the case with the RC! Why not?
I'm using Ubuntu 10.04 LTS and after recently changing a theme, all icons are stuck as GNOME defaults.I read some threads where it's only the folder icon that's stuck but as it is every single icon then I decided I'd best just ask.
View 8 Replies View RelatedSo when I install 10.04 LTS server with all the defaults. ie root parted with lvm, I get a grub error. Apparently the install script at the end of the installation does not take into account that I might install ubuntu on a different drive.
Without LVM, I can get it to work. If I drop down to shell and mount the root drive, then run:
grub-install --root-directory=/ /dev/sdc And all is good. But I want LVM on my boot drive. Does anybody out there know of an easy way of doing this? This really should be a bug. But I'm too much a noob to know where to issue this.

View 3 Replies View RelatedSo I just had gotten to know the old Grub a little when I upgraded Ubuntu to find the new Grub, which I barely understand at all! My use of Ubuntu is mostly for learning and recreational as my bread and butter is working on people's messed up Windoze systems, since that is where the work is. Naturally I've got to use and work with Windoze to know how to fix it and keep it running cleanly, but Ubuntu was the first Linux I found that to me seems like something that could be potentially be embraced by "non geeks". I have as yet to get anyone to try it; it is all about keeping up with the Joneses and having what they have. There is also that old pervasive myth that you get what you pay for, which with computers, I find the opposite is so often true, that the good stuff is mostly free.
In any case I dabble a lot with Ubuntu for fun and personal knowledge, but since I put 10 on I had only Windoze 7 on my machine at the time. It picked it up and I purposely installed Grub to my Ubuntu drive (I used separate physical drives, so that if you removed the Ubuntu drive, 7 would boot as if Grub and Linux were never on the machine and that is the way I like it since I tinker a lot.). The trouble is that I need Win 7 to be the default and I don't know how to do that with Grub 2 (is it 2?) I used to know with the old one. Also, I have since added a 160GB PATA drive with XP on it, since so much of the help I am asked to give over the phone is with XP and I am not one who can talk others through things unless I can see it myself. Plus there are some things I do that just plain old work best with XP. So I also need to add XP to my boot menu, and it is, on a separate physical drive as well, and I wanted that the same too; if you made the XP drive the priority boot device it will boot XP as if it was the only OS on the machine.
What the ideal for me would be is to have the Ubuntu drive as the one it boots from, Windoze 7 to be the default OS, and XP to be on the menu too. I have been able in all of the time with Ubuntu and Linux in general to find precious little info on how to do things with multiple physical drives. It seems to be taken for granted that the only way people multi boot is with separate partitions on a single physical drive
I have set up an HP 5M networked printer. The test page works fine, and the defaults are all set correctly. But when I try to print from my own java programs, the paper size is set to letter, and the margins are all set to 2.54 mm. I can change the paper size to A4 (but I have to do it EVERY time). And the margins won't even let me change them. I type in 0, click in the next field, and the value changes straight back to 2.54. It has been this way for at least the last two releases of Ubuntu.
View 4 Replies View RelatedI finally have a working nautilus after weeks experiencing a seg fault caused by a dependency problem which I have only now managed to resolve.
It came right after doing this:
Code:
gconftool-2 --recursive-unset /apps/nautilus
I then removed nautilus-elementary ppa and downgraded the nautilus-data.
Problem is the nautilus I get is extremely minimal -- really just a window -- which insists on opening new windows whenever I click on a folder.

I've tried removing .nautilus on several occasions.
What are the default settings?
Is there a more convenient way of editing nautilus?

I set up my interfaces file just fine on one of my computers and everything works. On my desktop its a no go. This is what I've done. I set my interfaces file to look like this
Code:

Then I uninstalled network manager (sudo apt-get remove network-manager-gnome). Now I can restart my computer, but I do NOT get a static IP of 112, instead I get the last working dhcp given address (.104). It connects and I get internet using .104.
BUT, if I run
Code:
sudo /etc/init.d/networking restart
then it DOES work. It changes to my address .112 and the internet works. But when I get that I get an error SIOCDELRT: No such process found (or something similar to that). But after it sits, it still finished with [OK] and my internet works. Clearly something is amiss though. Because it doesn't go to the static IP imediately. I even tried setting up a rcS.d link to a file with that networking restart command, but still no go. It starts with the .101 IP.
On Ubuntu 11.04, I have a need to use gnome-open from another application to open files in assigned applications. I think I understand how mime types are given in /usr/share/mime. I understand how default application associations are done in /usr/share/gnome/applications/defaults.list. I understand how update-desktop-database is used to maintain defaults.list. I know how to specify file associations (open with) from Nautilus. I understand how ~/.local/share/applications and ~/.local/share/mime override the system settings. I get all that.
What I don't understand is why the command gnome-open or double-clicking a file in nautilus, for certain file types (e.g. PDF), generates an error message:
Quote:
Could not display "<whatever file>". The location is not a folder.
The occurrences of application/pdf in the different applicable files all point to evince as the associated application.
By the way, mimeopen does work. What is the relationship between mimeopen and gnome-open? Manual pages for these commands are not helpful in understanding their operation.
In addition, I might throw in one other question. In the various .desktop files, I see that some application commands are enclosed in single quotes, but never the file name identifier, %f. If dealing with file/directory names with spaces in them, it would seem that quoting the '%f' would be important.
