Problem is, when I hook it up to my computer, the image will appear for 5-10 seconds then flash to a blank screen then show an image again. It is really annoying. I called ASUS tech support and they blamed it on my video card (typical). The funny part is that my computer has an ASUS motherboard integrated with an ATi graphics card. Since tech support was no help (as usual), I decided to come here. Is there a driver or something I can install to get it to stop doing this? It's really annoying.
Here are some stats in case they're needed:

Hi Team,

I wanted to install Ubunutu on my laptop and it currently has windows vista installed on it. I tried to install Ubunto 9.04 using wubi installer and everything went fine and I selected Ubuntu from dropdown menu after the system restarted. But when the sytem shows the username page to login the KEYBOARD and MOUSE are not responding. i tried the following commands but none of them really helped.

CTRL + ALT + F3
Or any other key F1-F12

I then uninstalled ubuntu from add/remove programs in vista and then tried to install Ubuntu 8.04 but the same issue happened while trying to login. Keyboard/mouse not responding.

I am using Lenovo Y series laptop and using the inbuilt keyboard/mouse.

few months ago i was trying to install Ubuntu using virtual PC on my office machine. even then i had similar issue with keyboard/mouse and somehow i fixed the issue by following some instructions i saw in one forum. But i lost that information now.

Any help will be greatly appreciated.

Thanks and Regards,

It's a fresh install. It installed GRUB, which works great, but with the 9.04 install I could customize the Grub menu (color, default OS and timeout) by editing /boot/grub/menu.lst. That file is no where to be found on this install. I've searched and all I find is reference to this file for customizations. Do I need to create it or is there something new out there? ]]> Ubuntu dday http://www.unix.com/ubuntu/123336-grub-customization.html <![CDATA[Can't update or use package manager -- gpg error]]> http://www.unix.com/ubuntu/123074-cant-update-use-package-manager-gpg-error-new-post.html Fri, 06 Nov 2009 04:35:33 GMT Code: --------- W: GPG error: http://archive.canonical.com karmic Release: Unknown error executing gpgv W: GPG error: http://us.archive.ubuntu.com karmic Release: Unknown error executing gpgv W: GPG error: http://us.archive.ubuntu.com karmic-updates Release: Unknown error executing gpgv W: GPG...

This occurs on using the update manager, package manager, apt-get update, etc. Any ideas? I've tried deleting the cached files, changing my server, checking that my date & time are correct (signing can be time sensitive), updating gpg (it was already at the latest), and maybe some other things I've forgotten.

Here's what I have tried so far:

1)
/etc/postfix/main.cf:

Code:

default_process_limit = 200

2)
/etc/postfix/master.cf:

Code:

smtp inet n - - - 200 smtpd

3)
/etc/postfix/master.cf:

Code:

smtp      inet  n       -       -       -       -       smtpd

   -o default_process_limit=200

During heavy traffic or simulation (stress test), the number of smtpd processes reaches the default limit, whereupon the server stops accepting new connections:

$ ps -u postfix | wc -l
101

N.B. There are no other bottlenecks in this state (according to atop).

Error messages:
warning: process /usr/lib/postfix/smtpd pid 25834 exit status 1
warning: /usr/lib/postfix/smtpd: bad command startup -- throttling
setuid(105): Resource temporarily unavailable

/etc/security/limits.conf:

Code:

postfix        soft    nproc   200

postfix        hard    nproc   300

Could any of you give me a hint, please?

Well, evidently the directives in limits.conf are completely ignored in our distribution/setup.

As a temporary solution, I placed "ulimit -u 300" in the Postfix init script.
300 smtpd processes can now be spawned, even though the process limit in master is only 200 (!). ]]> Ubuntu jonash http://www.unix.com/ubuntu/122592-smtpd-process-limit.html how to insert JPEG on each side of the cube using openGl http://www.unix.com/ubuntu/122089-how-insert-jpeg-each-side-cube-using-opengl-new-post.html Mon, 26 Oct 2009 04:33:29 GMT Hi all, i have the program to rotate the cube using openGL. i want to insert J PEG on each side of the rotating cube using openGL in C... please guide me,,any answer will appreciated..
