Hi All,

I am a linux user for past 1 year. I was using Ubuntu 9.04(32bit) and yesterday I updated it to Ubuntu 9.10(64bit).
From that time I am having a problem with display.
My monitor is HP 1740 TFT.
The screen freezes, key board hangs and the only way out from that is to force reboot the system.
I searched for the /etc/X11 directory and not able to locate the xorg.conf file.
I tried reshuffling the screen resolution and that too din't work and Ubuntu is not able to grab my monitor as always it says "Unknown Monitor".

user@ubuntu910X:/etc/X11$ ls -lt

Please suggest me a fix, I don't want to move out of Ubuntu.

Thanks

Boot into single user mode
Type" dpkg-reconfigure xserver-xorg && startx" to test the install. If you are use a proprietary driver, you will need to reinstall and reconfigure the driver for the present kernel.

In the xorg.conf file, you may need to manually enter the values for your monitor. The values for HorizSync and VertRefresh should be easily accessible from google or any search engine. Add the Monitor name and model also.

Hi Mr-Bisquit,

Thanks for your quick response.
I had already tried out the suggestions that you had mentioned and it giving the same problem again.
Today I faced some more kernal type of issues that automatically reported to ubuntu team.

Here I had taken the out put of some of the linux commands (dmesg,lspci-vvnn,uname-a,version) and provided the link for you to check. Hope this data will be more useful to analyse the issue in a better way.

Also please suggest me where I can contact to fix this type of kernal.

Found this in the ubuntu bugs (launchpad):

I found a workaround to this issue for those of you who have an intel graphic card (which is what HP Pavillion PCs come with).
you must revert to an older version of the graphic card driver by following these instructions:
https://wiki.ubuntu.com/ReinhardTart...telDriverTo2.4
The instructions were intended for Jaunty but they also work for 9.10
Of course, since the system hangs, you need to start in recovery mode to run those instruction from the command line.



Seems to be a problem that a lot of people with Intel graphics chipsets are having. Will try it this evening when I get home. Hope it helps everyone.

Mr-Bisquit

Are you using Xen? Your dmesg output shows a paravirtualized kernel booting.

Hi arisp, will try you suggestion and update you.
Mr-Bisquit, I am not using Xen.
If nothing works out I am planning to go back to Ubuntu 9.04, 32 bit.

Thank you Arisp!
for copying and pasting my comment from another post (https://bugs.launchpad.net/ubuntu/+bug/461163)

I guess you did it because it solved your issue which is the main point.

Sorry Julien... can't really tell if your tone is ironic or not

Just to make it very clear though, it wasn't my intention to pass your comment as my own comment. I started my post like this:

"Found this in the ubuntu bugs (launchpad):"

I pasted it here as I had found 2 good threads (this one being the one and the other being one in the ubuntu forum) with loads of people having this problem and no one having the faintest idea about how to solve it! It was only after searching for very long that I came across your comment on launchpad and thought it might be more helpful to post a potential answer to the problem here where more people seem to be looking for the solution. You'll find that I've made exactly the same post in the ubuntu forums.

In any case, I haven't had the chance to try it yet, so I was kind of hoping to get some reaction from someone who has as well. Will try make some time and try it tonight. Will post back if I get any luck.

As mentioned by someone else on launchpad however I can't believe so many people are having the same problem and the ubuntu developer community hasn't come up with a bug fix. It is a shame for people to have to go through hoops to get a linux distro to work. Eventually it will drive people away.

Thanks,
A.

I had two freezes this past weekend while using Firefox and one freeze today while using Gnucash. The only way to escape, was to hold in the power button to re-boot.

I have a fresh install of Karmic with an Intel 82845G/GL integrated video (according to the Xorg.0.log).

---

It may be worth noting that the Xorg.0.log showed an error trying to load the "i810" driver, which it couldn't find. Also, I noticed that Extreme Tux Racer is running somewhat "choppy". I assume this means that graphics acceleration is not active.

The procedure described above solved my problem! No more crashes for me.

Hope it works for other people too.
