What does going into tty1 then back to tty7 fix the colors? what does it do?
I mean the other things are nothing but stuff that ubuntu should change in
xorg.conf by defaut but the screen switching trick to get colors working is so
simple and shocking that I kicked my self in the rear end because I spent SO
much time online reading everything and NOT ONE PERSON had anything....there
wasnt even a bug for it from what I could see....am I the only one that uses
i815???
** Description changed:
This is my first post here so be nice I'll fix anything
wrong...format...grammar...extensive descriptions...
Okay here goes:
I own a Dell OptiPlex GX150 (slim case aka space saver model)
Main problem:
Cannot play 3D rendering games or use 3d desktop effects. 4 bugs to fix to
make it work.
After bug fixes:
still cannot use desktop effect...but games work fine.
Bug # (1)
Ubuntu is refusing to put into xorg.conf information about the video card...
Ubuntu just puts in "configured device" and "configured screen" etc...
which causes 3D games to multiply 3-5x on the screen looking like multiple
screens on top of each other side to side...
not playable.
Fix # (1)
open terminal and enter:
gksu displayconfig-gtk
set up your display (choose brand and model)
- set driver to the appropriate driver "i810"/"i815/intel"
- # I have used both the i810/intel drivers with no problems!!!
+ set driver to the appropriate driver "i810/intel"
Bug # (2)
when Ubuntu is first installed out of the box, direct rendering does does
work but slow...but after you setup the info in xorg.conf from Bug # (1) the
default Depth is 24 and causes Direct Rendering to not work...
Fix # (2)
# !!!NOTE: ONLY AFTER FIXING BUG # (1)
manually edit:
xorg.conf
and under:
Section "screen"
change:
Default Depth 24
to:
Default Depth 16
# !!!NOTE: There is also another option to change from 24 to 16 but i
deleted it and works without it just fine.
# If you don't delete it make sure to set it to 16 also!!!
#
# THERE IS A WAY TO HAVE ONE AT 24 AND THE OTHER AT 16 and vise versa
# BUT ITS REDUNDANT!
# (DEPENDS ON THE DRIVER USED...I dont know why it works...but its
does...)
# here is the proof use this:
# using "intel" driver you can use:
# Section "screen"
# Defaultdepth 16
# SubSection "Display"
# Depth 24 or 32 (or whatever and it will still work...)
#
# BUT using i810 driver it wont work...
# for some reason one driver will ignore it while another wont...
# !!!NOTE: If you use "gksu displayconfig-gtk" and save again your
settings
# that you will entered here in this fix WILL BE ERASED!!!
Bug # (3)
- Ubuntu does not the proper system memory to i810 i815 video cards for best
performance...so for some games 3D rendering is SLOW!!! (Sauerbraten)

# NOTE: Glxgears will seem to work nice and fast...when you try to play a
game like Sauerbraten it will be SLOW...
Fix # (3)
manually edit xorg.conf
AND UNDER:
"Section "device"
ADD THIS:
VideoRam 10000
- # !!!NOTE: 10000kb is the lowest recommended value in kb and 16384kb
(16mb) is the average recommended.
+ # !!!NOTE: 10000kb is the lowest recommended value in kb and 16384kb
(16mb) is the average
+ # recommended. BUT IF YOU USE THESE RECOMENDATOINS AND DONT GO HIGHER
SOMEGAMES
+ # WILL STAY SLOW
+ # I HAD TO ADD 400MB TO GET 10-60fps IN SAURBRATEN...
#
# I am currently using:
# VideoRam 409600 # (400mbs)
# You may question why even bother giving more than recommended?
- # Well the more I added the more FPS I got. (may have to due with the
lower possible desktop resolution...)
- #
- # DIDN'T TEST ANY HIGHER...I WAS GETTING 18-28fps!!! good enough!!!
+ # Well the more I added the more FPS I got.
+ # DIDN'T TEST ANY HIGHER...I WAS GETTING 18-28fps average!!! good
enough!!!
+ # If you lower your desktop to about 800x600 you can get a bit more speed
out of the game. I dont know why.

settings

-
-
- # AGAIN: NOTE: If for some reason you HAD to use an incorrect driver in
Fix #2
- # The highest possible DESKTOP resolution will depend on how much memory
you give to the VideoRam option.
- # I believe this is some error/incompatibility with handling memory with
individual drivers...
- # So if you have too little system memory your higher resolutions will
not be available.
- # So I believe with the "intel" driver my limit was as follows:
- # with 400mb set for VideoRam, 1200x1024 is the highest
DESKTOP resolution possible.
- # give or take a few Mbs.
- # !!!NOTE: You can still have in game resolutions that are higher than
your highest DESKTOP resolution possible with memory constraints.

Bug # (4)
When I play any 3D game the colors are HORRIBLE...
everything looks like 16 color mode not 16bit (bpp)
Fix # (4)
PRESS "Ctrl+Alt+F1"
THEN "Ctrl+Alt+F7"
thats it. I promise.
# this was a VERY tricky to fix...
# sometimes when I changed a setting in game it would fix itself for that
one game...
# untill the game is over then you start over with 16 colors...
# very annoying..in tremulous average game is only 20 mins....
# But:
# most of the time if you just played for about 5-10 mins it would all of
a sudden just fix itself...
# which is what I would normally do....
# it looks like memory problems...but its not!
#
# well...
# while messing with xorg.conf and freezing the desktop and screwing up
the screen
# I would keep going to "Ctrl+Alt+F1" fixing xorg.conf and manually
starting "startx"...
# I had to at one time manualy start "startx" again from the tty1
terminal..
# then when i got on the desktop i tested my settings (glxinfo for direct
rendering and glxgears)
# then jumped into tremulous again
# and while I was in the game it I pressed "Ctrl+Alt+F1" and fixed
something in the xorg.conf...
# and went back
# BANG!
# THERE WAS PERFECT 16BIT COLOR (NOT 16 COLORS!!!)
# a new game eventually was started and i was again stuck with 16
colors...
# so I tried it again and it worked...
# consistently.
# every time!
