Fedora Security :: Can't Get Kde Login Banner To Display On F12
Dec 8, 2009I'm trying to secure a workstation according to the DISA STIG and updated this machine from f10 to f12 to take care of a lot of kernel and openssl vulnerabilities.
I've gone into the Login Manager by running /usr/bin/kcmshell4 kdm --lang en_US as root, turned off themed greeter to enable the Dialog tab and inserted the login banner in the Greeting field. I checked the Xresources file in both /etc/kde/kdm and /etc/X11/xdm and the xlogin*greeting: field has my banner.
However when I restart the machine I am not prompted by the banner and when I select a user I am not prompted by the banner.
I'm not sure if this could be the issue but I get errors when launching kcmshell4:

Jan 25, 2011Having a little issue with creating a login message banner in RHEL6 that uses two buttons. One for Accept which logs the user in. The second for Cancel which immediately logs the user out. I've modified the /etc/gdm/PostLogin/Default file to have the script, posted below, and it worked perfectly fine in RHEL5. But in 6, when you click Cancel, the user is still able to log in. It even states in the system logs that the user cancelled the login.As you can see, I have the script using the 9th field of the user's env to get the PID, and using the kill command to end the process, which should be logging the user out right away if they click the Cancel button. This works in 5 without issue (though I used -f5 in RHEL5, had to move it to -f9 for RHEL6).

Ubuntu :: Display Driver Warning When Upgrading To 10.04 LTS?
Oct 16, 2010planning to upgrade to the next LTS version i.e. 10.04. Have already applied all the updates and got the system up-to-date prior to upgrading. But when the upgrade starts I get the following message: Upgrading may reduce desktop effects and performance in games and other graphically intensive programs.This computer is currently using the AMD 'fglrx' graphics driver. No version of this driver is available that works with your hardware in Ubuntu 10.04 LTS.
Do you want to continue ?Obviously, I clicked on NO and got out.What gives ? How come an upgrade is supposed to DEGRADE performance ? What kind of upgrade is that ? Also what is the implication for me ? Will I have to happy with 8.04 forever ?The machine in question is a Toshiba Satellite A100. I use GIMP quite a bit on it, so problems with graphics intensive applications is kind of worrying.What am I supposed to do ?? Upgrade anyway or stick with 8.04 ?

OpenSUSE :: Gtk-WARNING **: Cannot Open Display: :0
May 29, 2011For example, the gparted application menu item doesn't work; using it means that there is almost no filesystem support. The only way to get it to work is to open a terminal, run 'su -', and then open it from there.As another example, I tried creating a nautilus script to open files as root with a command like this:
Code:
for uri in $NAUTILUS_SCRIPT_SELECTED_URIS; do
gnomesu -c "gnome-open '$uri'"
done
When I try using it, it just fails. Typing out the command in the terminal gives this (tested on a text file):
Code:
No protocol specified
(gedit:13672): Gtk-WARNING **: cannot open display: :0
I'm pretty sure the problem is that it's granting privileges, but not using the full root environment, or something along those lines.

General :: Cannot Configure Three Monitor Display Ubuntu?
Jun 17, 2010Looking for a newb-type step by step process for configuring ubuntu to 1) recognize both the onboard video card as well as the PCI graphics card and 2) how to set up three displays with separate desktops (able to mouse-over from screen to screen). So far the 20+ hours searching online has yielded excessively complex instructions, inappropriate instructions, or ancient posts. Is this config even possible? Again, I am learning so the instructions need to be very deliberate. PNY GeForce FX 5200 PCI 256 MB 2 Port VGA + S-Video Graphics Card VCGFX522PEB and an onboard display apdapter (Intel P4 Chipset 845GV).

Ubuntu :: Unable To Configure Display / Can't Choose 1600x900 On Either One?
Oct 7, 2010Karmic 9.10 latest updates
Nvidia GeForce 6150 LE
Nvidia driver 185.18.36
Monitor Acer P205H - 1600x900 native
I can't configure the monitor. and the display.
I've tried with both the built in display configure and the Nvidia one. Can't choose 1600x900 on either one.
I either can't see all the display on the monitor, or it takes on some weird panning mode and looks like the display is about 2500x1500 or something.
Here's the xorg.conf file. Clearly it does not see the new monitor and the modes are wrong. These settings are for the previous monitor. How Can I fix this so that my display works properly? Thanks.
