I've had this problem since edgy eft and I think it's time I've posted this here.
Currently I'm running 8.04 64 bit, but I have this problem on 32 bit as well. On a clean install everything works fine, but after I do the first upgrade and reboot I get the low graphics mode error thing. However if I stop gdm and reinstall my drivers it works fine.
I have a 7600 GS.
I'm trying to figure out what in the upgrade causes this and how to fix this, I hate having to reinstall my drivers after every boot.
If you need the output of anything let me know and I'll get it here pretty quickly.
Thanks in advance.
Edit: I have a dual monitor setup.
