Hello
I have the Ububntu Dapper PPC cd and am using the kernel ubuntu_d_inst to launch the installer. (I cannot use the grub stuff as my main boot partition is FFS) The installer goes well up until it gets to step 5 after setting up the HD partitions. When I go to select "forward" after setting my partitions (USing manual partitioning) it crashes, nearly every time. Its very frustrating. Can somebody please help?

Also, if I select "use largest unallocated space" it goes to page 6 of 6 of Install but the partitions its going to format and install to are listed mathematically incorrect and I'm afraid to install.

It crashed for me too, always.

Using "largest free block" worked fine for me, even if printing some strange numbers. Even if it worked for me fine it's always good idea to make a backup before installing a new OS :-)

Thanks alot. I risked it and it worked (the installer makes up some randomly generated number for the formating of the partition which is wrong.)

2 questions

1. how can I get 1280x1024 screen mode @60hz plz? It only goes to 1024x768

2. How to get the Scroll wheel to work with ps/2

1 - edit xorg.conf and add the missing screen modes

2 - not sure, probably in xorg.conf too, there's a section about the mouse. But usually it works out of the box.

Usually, for adding the scroll wheel you have to add the following option to the section for the mouse:
Quote:
Option "ZAxisMapping" "4 5"
Note the space between the 4 and the 5.

Once you've added that, save the xorg.conf file and restart X.

Thanks for the responses

I edited the x.org config and added "1280x1024" in the screenmode section but I don't get this choice in the screenmode config on the desktop??? Should I modify the frequences of the "General Monitor"

PS/2 wheel working now as well as libdevcss ;-)

Hi magnetic,

Just edit the xorg.conf to look like this for the part Section "Screen":
Code:
Section "Screen"
Identifier "Default Screen"
Device "ATI Technologies, Inc. RV280 [Radeon 9200 SE]"
Monitor "Generic Monitor"
DefaultDepth 24
SubSection "Display"
Depth 1
Modes "1024x768" "800x600" "640x480"
EndSubSection
SubSection "Display"
Depth 4
Modes "1024x768" "800x600" "640x480"
EndSubSection
SubSection "Display"
Depth 8
Modes "1024x768" "800x600" "640x480"
EndSubSection
SubSection "Display"
Depth 15
Modes "1024x768" "800x600" "640x480"
EndSubSection
SubSection "Display"
Depth 16
Modes "1024x768" "800x600" "640x480"
EndSubSection
SubSection "Display"
Depth 24
Modes "1280x1024" "1024x768" "800x600" "640x480"
EndSubSection
EndSection
After saving just do, Ctrl + alt + backspace and X should restart with the resolution 1280x1024 if you have choosed a 24bit display. Maybe that was what You did ?

When we are on it, maybe You might want to try:
Code:
Section "Device"
Identifier "ATI Technologies, Inc. RV280 [Radeon 9200 SE]"
Driver "ati"
# BusID "PCI:1:8:0"
# Option "UseFBDev" "true"
Option "BusType" "PCI"
EndSection
Turns on direct rendering. If you are using a Radeon graphicsboard ?

Hey Gunne

Thanks for the response. Yes, I added 1280x1024 under the "screen" section and commented out the changes in the "device" section (direct render? how do you mean) However, that does NOT give the screenmode. I had to comment out the Horizontal and Vertical Frequency fields under "monitor" that was the problem.


magnetic

nice kybrd shortcut for X reset btw :D

magnetic,

Ok, good.

Option  "BusType"  "PCI"

in section device will/should enable 'Direct Rendering'.

You can see if its enabled if You run the command - glxinfo

Either it tells Direct Rendering is enabled or not. (yes or no)

Its little bit better when running 3D applications if Direct Rendering is enabled.

Remember to restart X for enabling of every change made.

I ran glxinfo and it shows direct rendering set to "no". I cannot understand the command you just posted as a couple of the characters are corrupted?? Also, did you see my post about 3d not working at all (*looks like soft render) for me here??

ps good to see you so active here :-)

magnetic,

Ok, Im posting from Linux instead, maybe will make it better.

(Hmm, something strange in the forum ?)

Yes, I saw You post about 3D. In xorg.conf in Section "Device" add the line:

Option "BusType" "PCI"

So it will look like this:
Code:
Section "Device"
Identifier "ATI Technologies, Inc. RV280 [Radeon 9200 SE]"
Driver "ati"
# BusID "PCI:1:8:0"
# Option "UseFBDev" "true"
Option "BusType" "PCI"
EndSection
This will enable Direct Rendering. You can also disable UseFBDev as I made above, no need for it.

After You changed and saved, restart X by the command I posted above, and Direct Rendering should now be activated.

Best wishes,
Gunne

Thanks alot. Ok. direct render is on now. But my God its slow. WIth this same radeon 7500 and Debian 2.6.10 kernel I was getting 400+ fps with glxgears and 3d games were fast. Gears is very slow with ubuntu and games are slow. Here is my glxinfo now:

Hi magnetic,

No problem ! :-)

Hmm, I doubt that You can see any over all performance difference between different linux systems.

But You are free to prove me wrong ! :-)

Of course I do understand that if a specific code is written for taking benefit of some specific registers in a chip, like for instance the AltiVec unit in the PowerPC chip, You will notice a performance increase in the specific application using the code.

Also remember that for instance a 3D-driver made for a specific graphicsboard by a specific graphicsboard-manufacturer will show the best possibilities and performance with the specific graphicsboard. But as You also know, there is no graphicsboard-manufacturer that makes driver for a specific graphicsboard that can be used with our PegasosPPC platform.

Have a good day !
Gunne

I appreciate your post, but you are stating things that of course I am aware of. (And you should know that!)

What i'm saying is my previous Debian install with 2.6.10 kernel and this very gfx (Radeon 7500) was giving me 400fps with glxgears and fast 3d performance whereas it seems much slower with this Ubuntu Dapper build...

magnetic,

Yes, I know :-)

But then we should try find out whats causing the difference to be.
