hello ashesh0326,
To be honest it looks like your problems are spinning out of control(just my opinion) with suse 10..
I run a desktop with a hard drive plug in rack with many drives..I have windowsXp dual boot with suse 10.2 on it,another with Suse 10.2,another with suse 10.0,yet another with Kubuntu 6.1 and Fedora Fc5 as well as Mandriva 2007 free..Not to mention the live cd versions..Yes I love Linux,hehe Out of all the above the Mandriva seemed to install with the least trouble on my particular system..That will vary with your hardware and likes and dislikes too..
Others may disagree but heres my impression for the following:

Suse:Pros...Very complete distro with lots of packages
Cons: Been somewhat difficult to install trouble free on my computer..Slow compared to others in booting and
very slow in upgrading patches etc..
Kubuntu: Pros installed easily,but found it somewhat different from the others (user/root way of doing things)..Killer update system..Very very quick..
Cons: I guess just my unfamiliar way to do things in it..

Mandriva: Pros: Installed easily and it found all my hardware first time..Nice assortment of packages too..Upgrade with urpmi worked well too..

This is not to start a flame war but just my observations for what it,s worth.
Finally, ashes,you deserve a lot of credit for persistance
and it's clear you really enjoy Linux..Even if you do not eventually solve it I think you learned much,I know I did from the fine posters in this thread..Have Fun

Hi,

Sorry to hear Fedora wasn't much of an improvement. I'd just like to point out that you may have missed quite a few packages: my dvd does allow me to install Gnome, XFCE or KDE (or all three at once if I want to). So why not you? You should 've chosen "customize now" right after setting up the system clock if you wanted to add to the default install. I'm quite confident the bind packages were there too.

Still, that wouldn't have solved the display issue. I'm afraid all of this is due to hardware limitations. I would be tempted to single out the video card but then I find it's supposed to support up to 2048x1536:scratch: And I have indications that it is possible to run your monitor at higher resolutions too; you may want to compare your xorg.conf with what you can find here (I guess you most be sick and tired off all that xorg stuff by now):
http://linux.derkeiler.com/Mailing-L...5-10/2794.html

In the end, if neither Suse nor Fedora does the trick, I'm afraid that you'll have a hard time finding a distribution that does offer what you're looking for. Let's not forget that below the surface, all distributions are quite alike and xorg is something that unites them all (possibly with the exception of Slackware). As a huge Debian fan, I would recommend Etch as a valid alternative; but that one uses xorg just as nearly all the rest so I really don't know.

ashesh0326 03-27-2007 12:34 AM

Well, thank you so much guys, I really really appreciate all the help and time you have given.
And yes, I kept thinking of something that I had seen during the install, and yes, it was the customize now option. So, right after I had posted my last entry here, I suddenly made up my mind to give Fedora Core a try. I started the install, and hit customize now, and tadaa!! The options were there. I selected all that I needed and proceeded. The install went fine, and much faster than it did in Suse's case.
Once done, I first got rid of the 1280x1024@60 screen (trust me, it really hurts your eyes), and went for a decent 1024x768 screen.
Configuring the system was a breeze too. I had no problems when it came to setting up my ethernet and dsl connection.
Another interesting point was, this time, my system does give me a 1152x864@75 option, under System>Administration>Display, but its a different story that the system does not ever accept it.
Other than that, I'm quite happy with FC now. It somehow gives me a more open source feel, and its definitely faster, so good enough. I think I'm going to give FC a try before jumping into anything new now (though I'm aching to try Etch now that you've told me...)
And definitely, linux is one of my huge interests, and lets see if I can manage to get things working my way before I get new hardware. I really hope I do.
And yes, FC does come with some bugs. I had to go for a double install in this case, as after the first installation, FC jumped into 1024x768@60 (YES!! 60Hz!! I checked with the monitor), and even that is an eye sore. After reinstall, things worked fine.
As far as Suse goes, I don't know. Suse is something people keep falling back to, and maybe I will to. But the only reason why I've installed linux is because I've wanted to learn more about computers and how things work at the basic level. And I think Suse keeps you from doing that. It's highly GUI based, and my experience with the whole sax thing has made all that pretty clear now.
So, maybe Gentoo is next for me, but it's also scary, as people tell me that a lot of customization goes into setting up a Gentoo based PC. And since I need a working system 24/7/365, I really doubt myself. Hehehe... But I love trying new distros.

Anyways, thanks a lot guys. You've really helped me gain a lot of insight about the xorg.conf (jay73: I'll give what you've written a try though, and will let you know asap) thing, and it's really good to see both of you being so willing to help me.
I do wonder if there is some other way to keep in touch with you all. If there is, please feel free to let me know, and please ignore this if you're not willing to.

Thanks again!

Period.

Before I had a few extra systems, I had to keep my PC able to run at any moment too. A lot of people will tell you to dual boot, but sometimes things go haywire and eat the other os too. My solution was to buy a couple of removable drive drawers (with hard drives). Changing OSs then meant: shutdown, turn key, pull out one drive, put in the next, turn key, boot next os. This makes certain that the worst you will have to do is shut the machine down and reboot(to get a running machine). The drawers are usually only $15 each and for testing purposes you can run any hard drive you have laying around. At one point I had drives for win 3.11,95,98,XP and OS/2. It makes it a lot easier to trouble shoot(over the phone to relatives) an os if you have it booted in front of you.

For FC specific problems you may have better luck over at fedoraforum.org.

ashesh0326 03-27-2007 06:23 AM

Lazlow,
Thanks for the advice man, and I certainly I agree with you on that. I completely understand the risk of losing the other OS while installing linux. In fact, when I first installed linux, I did it with FC 2, and trust me, the installation was itself challenging. First, you have to get used to completely different terminology, and second, you have to be extremely careful when formatting hard drives is concerned. One mistake and whoom! It's all over for the other OS. I do agree with you.
I have been thinking of the alternative you told me too, and well, maybe I am going to invest in it pretty soon. It seems like a workable and risk free operation to me, and I've been thinking of buying some new hard drives.
Lets see. Thanks for the words though. I appreciate your help!

ashesh0326 03-27-2007 11:46 AM

By and by, any of you guys know how to set up and activate power management in GNOME on an FC 6 machine?
The powermanagement thing works well in KDE, but not in GNOME. I tried the xscreensaver thing too, but my system doesn't recognize the command, and it seems like it's not been installed.
Any ideas about that?

Bad news on Intel 945

None of the monitors I selected there offered what I wanted. I first selected a monitor: 1152x864@75 Hz. I then looked everywhere for a 1152x864 setting, but it was nowhere to be found. Instead, my desktop started running on 1024x768@85.
Then I also selected other resolutions, but my pc never let me switch to what I wanted. I never found 1152x864@75 as an option anywhere... And there were no options with the frequency as well... :(
I don't know what to do... :(

Hi, ashesh.
I'm sorry it has been so long since I have responded. I was made a moderator on another Linux site and it's taken up all my time learning the job.

But what I have to say now is bad news. The Intel driver for the 945 chip uses the Video BIOS to set video modes. Only the preset modes allowed by the BIOS are going to work. This probably what you are hitting up against.

See
http://lists.freedesktop.org/archive...st/009197.html

I don't know if this will help or not, but you should look at it:
http://en.opensuse.org/Patch_the_Video_BIOS
and Intel's page on Linux support for the chip:
http://support.intel.com/support/gra.../CS-010512.htm

Sorry if that is the way it works out. I wish I had better news for you.

BTW, if you are interested in trying a different Linux distro, Simply MEPIS 6.5 will be in Final Release in a week or less. Here is the Release Candidate 3 statement:

I think this is what you have in mind:

http://www.gnome.org/projects/gnome-power-manager/

Have you got HAL installed?

And if you want a screensaver, it should be as simple as going to System/Preferences(or was it Administration?)/Screensaver; although I think a screensaver is enabled by default (it was on my system but I may have made a different selection).

And here are two online tutorials that I found immensely helpful in first setting up and configuring FC5 (and more recently FC6); the first one is by Stanton Finley, who made quite a reputation by writing these how-tos; unfortunately (for Fedora fans, that is), he decided some time ago he likes Ubuntu better so there has been no follow-up for FC6 - but most of it is still perfectly valid. The second one addresses FC6, it largely repeats Stanton Finley but it's got some very interesting information of its own.
http://stanton-finley.net/fedora_cor...ion_notes.html
http://www.mjmwired.net/resources/mjm-fedora-fc6.html

And if that's still not enough, you can look around for one book I keep recommending to everyone who is new to Fedora (especially if they take a special interest in the server aspect):
Christopher Negus - Fedora 5 and Red Hat Enterprise Linux 4 Bible
Not available for FC6 but last time I checked there was a new edition cooking for Fedora 7 ; although that may still be a while in the making because Fedora 7 shouldn't see its official release until late May/early June (although you can already download release candidates).

ashesh0326 03-28-2007 10:56 AM

Well, thank you so much for the information SilverBear, I appreciate your help.
But, then, the BIOS presets you've talked about here, refer to the allowed resolutions as programmed in the BIOS, right? I gave it a thought, and I remembered that I had gone through intel's website, and found that my card was capable of a lot more (please refer to: http://www.intel.com/design/graphics/gma900/ ). So, is there some reason the manufacturers program the card with allowable modes that are less than what the card is capable of? If yes, then why? (please don't mind my asking, I'm just being inquisitive.) I'll really appreciate if you could let me know.

Jay73,
Well, I did check and yes, my system does have HAL installed. And the screensaver works pretty fine, its just that the monitor does not get turned off at all when I'm in GNOME. Things work perfectly in KDE though. Any ideas about how to enable turning off the monitor by the system? (I can reach the screensaver settings, and get the options there about enabling/disabling the screensaver, and also for choosing different ones, but nothing about powersave. I also noted that my when my FC loads, it does load the HAL Daemon.) Thus its pretty much beyond doubt that my system has HAL Daemon, I just need to know how to activate it, and possibly change the values of idle times in it. ;) And if you think I'm bugging you too much, please feel free to ignore me, haha!! (I'm sorry, but I've already asked you for a LOT of help, and I don't know how to thank you.)

Anyways, I'm going to fiddle with things here for a while, and let you all know if I make some progress.
Also, there is another thing I'd like to share: I just got to know how powerful 'yum' can be, and trust me, installing things via yum can be serious fun! I had the time of my life configuring my system for mp3's and all, haha... It was serious fun.

And last but not the least, thank all of you so much!

jay73 03-28-2007 12:15 PM

Well, powersave mode is related to the DPMS option in xorg.conf. Maybe you could check whether you have

option "DPMS" "true"

under section monitor?

Note: I hope you had a look at those how-tos, they'll show you how to set up yum to download third-party packages; and that's where all the controversial and "illegal" goodies are - the best part of it all, in short.

Hmmm, thanks again. I can see that there is an option "dpms" under Monitor, but there's no true. Is that the problem?

jay73 03-29-2007 11:10 AM

Well, I suspect not, if it's there it's probably true by default. Still, explicitly adding "true" won't hurt in any way either.

ashesh0326 03-30-2007 11:34 AM

Its working now!! Thanks man!
