Nvidia 5200+Intel onboard graphics conflicting
@Pathik:
First,your vertical freq set for LG 505E monitor was inadequate;
Now,as you have completed installation with onboard
Intel graphics and put nvidia agp card inside,u may need to blacklist the onboard intel modules.
I agree that this is a serious unnoticed bug in Ubuntu
So,If you can follow below howto,try and reply here:
boot with "vesa" gfx driver to Ubuntu desktop.complete your restricted driver installation from "Restricted drive manager".
Now,backup ur old /etc/X11/xorg.conf.open a terminal and run:
Code:
sudo cp /etc/X11/xorg.conf /etc/X11/xorg.conf.bked
now in terminal,
Code:
sudo gedit /etc/X11/xorg.conf
enter below xorg.conf details.
Code:
# xorg.conf (xorg X Window System server configuration file)

^Edit your /etc/X11/xorg.conf to look like above;save and exit.
,PLEASE NOTE THE BUSID and VERTICAL FREQUENCY ENTRIES,also the loadmodule entry "DRI" is removed>it seems your onboard graphics is popping up creating problems
.so use the ugly hack i mentioned somewhere else :
open terminal and do as below:
Code:
sudo gedit /etc/modprobe.d/00local
add the following entries:
Code:
install intel_agp /bin/true
save and exit.restart your computer and see whether X loads?
Now,Open synaptic manager=>browse to status>installed .
now remove all xserver-xorg-video-* and xserver-xorg-video-all
except xserver-xorg-video-vesa.
select "completely remove and purge option" to remove these unwanted drivers off ur hdd.
lastly,
IMPORTANT STEP:
boot into
BIOS of ur comptuer.check and make sure onboard graphics is disabled and/OR select external Agp.
Also,the above xorg.conf is meant to give you a 800x600@85Hz which is,the maximum freq and effect available for a 15" monitor.
the vertical frequency source for LG 505E is:
*www.ebuyer.co.za/product/LG-15-505E-Studioworks-Monitor.html
^so dont panic if it is wrong freqeuncy
I,myself got a samtron 56V 15" with same freq.the best resolution available is 800x600@85Hz.
post your results.also if some problem occurs,post the output from terminal for "
lspci and
lsmod" commands
Best of Luck!
