I've posted everything I've learned about Ubuntu on the T42 on this page:

Corrections, additions, changes, etc. are always welcome.

OK, I've edited the file to add some wireless wisdom, but it isn't much...

Hi

and thanks for a great tutorial! I've got a couple of problems thou:

no screen confirmation

my fan is constantly on, althou the cpu-scaling is working

Could you give me some advice as to where to look for more info about this?

Thanks again!
/Michal

I'm sorry to say that "everything I know" did in fact mean "everything I know". If you find anything about the fan, please tell us!

I'm not sure what you mean about "no screen confirmation". If you are referring to the on-screen display of the effect of the ThinkPad buttons, the solution is on my "everything I know" page. Did you try it?

Hi again!

I did follow your advice, and most of the stuff works. The on-scrren notification works now. But the "A possible video speed boost?" does not. After editing xorg.conf the screen went black (LCD was on - but black).

Edward Mendelson · #8 Post by **Edward Mendelson** » Mon Jun 27, 2005 12:57 pm

Possibly your T42 has a different video card from mine. Maybe I should add a warning to my page...

AndreasMeier · #9 Post by **AndreasMeier** » Mon Jun 27, 2005 2:30 pm

@migo2137: what video card do you have in your tp ? And please be so kind and post your xorg.conf (the version where the LCD stays black).
I have exactly the same problem (LCD is on but black) with my ATI7500 card.
The only way to get it working, was to disable the options AGPFastWrite, PageFlip and AGPMode.
But dont know if I have to disable all of them,

@Edward Mendelson: To compare both, what video card do you have ?

Thanks to both of you,
kind regards,
Andreas

Edward Mendelson · #10 Post by **Edward Mendelson** » Mon Jun 27, 2005 2:45 pm

As it says at the top of the page that started this thread, my 2373JTU has the same Radeon 7500 that you have. However, I never get that blank screen. I'm away from the machine right now, but I'll try to post the relevant parts of my xorg.conf later.

AndreasMeier · #11 Post by **AndreasMeier** » Mon Jun 27, 2005 3:23 pm

What I have in addition in my xorg.conf is the Option "DynamicClocks"="true" to reduce speed and heat of the card.
With the disabled other options the card is running, with enabled options the screens stays black,
so I'm very keen on seeing your xorg.conf in order to compare it with my one.

Thanks you very much and hope to hear from you soon.
Kind regards
Andreas

benplaut · #12 Post by **benplaut** » Mon Jun 27, 2005 5:53 pm

what are you guys with Radeon 7500 getting in GLXgears? i'm not so sure that 730 is the max i can get out... performance was better in SuSE...

AndreasMeier · #13 Post by **AndreasMeier** » Mon Jun 27, 2005 11:38 pm

With my current settings I have around 350-380 fps.
Not much compared to your 730 fps, but honestly, we have here a Thinkpad and mainly I need that machine for business, so 3D is not that important for me, but nice to have. And more frames are even nicer

And by the way, chronium is limited to 50fps anyway

If you have 730fps, your video card is an ATI7500? Interssesting, can you post your xorg.conf also ?

Thanks and regards,
Andreas

No, you have dri enabled. look in modules section, there you have load dri and in den section dri, here is dri also mentioned.

One question to you too:
Can you do me a favor and enable the Option "DynamicClocks" in your xorg.conf, right underneath the Option "EnablePageFlip" "True"
and tell us, if you find your LCD sometimes black ?
If you disable the option again, all is working normally on my T42.
Perhaps you have to disable the synaptic touchpad section and the module to get it work.

You also have an ATI7500, or ?

Thanks in advance,
Regards
Andreas

@Edward,

why have you this:
# SubSection "extmod"
# Option "omit xfree86-dga"
# EndSubSection
disabled in your modules section ?
Why it is good for (if enabled) ?

regards
Andreas

Edward Mendelson · #19 Post by **Edward Mendelson** » Wed Jun 29, 2005 1:37 pm

I'd completely forgotten about that until your post. So all I can report here is what I can find from a Google search. I would recommend that you search Google for a lot more information about this.

It seems as if I must have this post, which I just found through Google:

http://ubuntuforums.org/showthread.php?t=29990

(make sure to read beyond the first post). But I probably read something else as well that I've completely forgotten.

Here's some more detail that I found on Google:

# This loads the miscellaneous extensions module, and disables
# initialisation of the XFree86-DGA extension within that module.

SubSection "extmod"
#Option "omit xfree86-dga"
EndSubSection

So, by commenting out the whole section, I completely disabled the extension to the module (probably no need to comment out all three lines - simply uncommenting the middle line would presumably be enout to "omit" - disable - the extension).

Now, what is the DGA extension? Google tells me that also:

"Uses the XFree86 DGA extension to do fullscreen direct framebuffer access on X servers which support this. For systems without kernel framebuffer support, the program must be run as root for this target to be able to mmap /dev/mem."

There's a lot more on Google where that came from. A quick search will tell you much more than I remember!
