Linux / Lucid Lynx Graphics workaround (temp)
« on: February 06, 2011, 07:18:30 pm »
Hi there,
my own 64bit Lucid Lynx Laptop (Dell Inspiron 1520, with onboard Intel graphics) and my son's 32bit Lucid Lynx PC (with Intel 1GB onboard graphics card) were having problems displaying textures in models properly with the 2.3.1~1~getdeb1 version.
The ships were mainly black (missing textures) and any personnel wearing body armour & helmets were displaying corrupted textures.
The only difference I found after a lot of fiddling with the settings was a slight improvement in the ship models when I turned 'Texture Resolution Cap' to 'Low', and 'Lightmap Blocksize' to 'Low'. The personnel textures were still corrupted.
I found some of the settings buttons didn't work (Texture Ansitropy Level = 0 and not adjustable, Texture Compression unchangeable), and changing the other settings like advanced GL shaders, made no difference to the problems.
After many attempts to correct this problem I decided to try the older Karmic version (2.2.1). This works flawlessly.
If you are experiencing the same problems, I recommend downgrading to the Karmic version by doing the following;
Uninstall all the 2.3.1~1~getdeb1 UFOAI files through Synaptic.
Next go to your 'Repositories' heading in Synaptic, and using the check boxes, temporarily disable the following;
http://archive.getdeb.net/ubuntu lucid-getdeb games
http://archive.getdeb.net/ubuntu lucid-getdeb apps
then add the following repository;
deb http://archive.getdeb.net/ubuntu karmic-getdeb games
then refresh Synaptic.
Now when you search for UFOAI in Synaptic you should see the 2.2.1 Karmic version and not
the 2.3.1 Lucid version.
I tried to install all the components (ufoai, ufoai-data, ufoai-data-music, ufoai-server, ufoai-tools).
I was unable to install the main UFOAI executable using Synaptic due to a 404 not found error so if you get
the same error, do the following;
Open a web browser and goto;
mirrors.fe.up.pt/pub/getdeb/ubuntu/pool/games/u/ufoai/
click on the following (32bit) to download it;
ufoai_2.2.1-1~getdeb2_i386.deb
or
ufoai_2.2.1-1~getdeb2_amd64.deb (64bit version)
When downloaded (you will need to close Synaptic for the next step), double click the file,
and an installation box should appear.
Click on install, then close the installer and re-open Synaptic.
When you search for UFOAI now, all the components of UFOAI should now be installed, and at
version 2.2.1-1~getdeb2. If not install the other components listed for ufoai.
In order to prevent this being upgraded to version 2.3.1~1 you will need to lock the version.
To do this select 'ufoai', then click on 'Packages', and then select 'Lock Version'. Do this for all
the ufoai files.
Next go into the 'Repositories' heading in Synaptic, and re-enable the getdeb repositories that
were disabled at the start of this downgrade. Close Synaptic when done.
For me the 64bit version I found at the above repository didn't work straight away, so I got an earlier version from
here;
https://launchpad.net/~gspreemann/+archive/ppa/+buildjob/1311355/+files/ufoai_2.2.1-0ubuntu0gspr4.2_amd64.deb
and double clicked it (invoking the package manager), and then installed it that way. I then installed the other ufoai
components through Synaptic, & locked the versions, then quit Synaptic. This resulted in not being able to find the
ufoai executable so;
I double-clicked the 'ufoai_2.2.1-1~getdeb2_amd64.deb' file I had retrieved earlier and this time it downloaded and
installed properly (hopefully it was a temporary 404 error so you won't have to do that).
Please note this is a temporary solution, and hopefully the later version (2.3.1~1) will be fixed soon.
