enabled "nomodeset" and then emerged xorg-server

LegionOfHell

I enabled nomodeset(because I was getting flashes during boot) in grub and then installed xorg-server

Then startx returned errors and pm-suspend refused to work properly (wouldn't wake up from suspend)..

Then I realized the mistake I had made...so I removed nomodeset from grub...

Now pm-suspend works fine but when I startx, I see a black screen with the cursor at top left..

Should I emerge xorg-server again like this :

emerge --ask x11-base/xorg-server

...what is the fix for this ?

Many Thanks

Post your emerge --info and GPU.

Here is the output of emerge --info :

here is the output of sudo lspci -vv :

These might be helpful too :

Xorg.0.log : http://dpaste.com/17EE3KZ (after "startx -- -logverbose 5")

these are the errors :

(EE) modeset(0): failed to set mode: Invalid argument
(EE) Failed to load module "intel" (module does not exist, 0)
(EE) Failed to load module "fbdev" (module does not exist, 0)
(EE) Failed to load module "vesa" (module does not exist, 0)
(EE) modeset(0): failed to set mode: Invalid argument

At the black screen, if I press alt+shift+q , I return back to command line...alt+shift+q is the key sequence for exiting dwm...

dmesg : http://dpaste.com/1S0DXGC

something tells me I should re-emerge xorg...

EDIT:

When I write config files under /etc/X11/xorg.conf.d/ this is how Xorg.0.log looks like :

This might be a kernel bug, people are talking about it everywhere..

I'm not sure how you can trigger this behavior just by toggling a nomodeset kernel parameter on and off.. Something else happened in between...

I basically did the following :

(1) enabled nomodeset
(2) recompiled the kernel
(3) installed xorg-server
(4) installed pm-utils
(5) pm-suspend wouldn't wake up from suspend.
(6) startx returned an error.
(7) removed nomodeset from grub
[8] suspend worked fine but now startx starts a black screen with a cursor at top left corner...

alt+shift+q works when trying to quit the black screen...it is the key sequence for quitting dwm...my guess is that it has something to do with the Intel driver.

Did you turn off modesetting in the kernel? I don't mean passing the parm to grub, I mean setting modesetting off in the config.

What does your xorg.conf look like?

I never touched any modesetting options when configuring the kernel...I never created/modified any xorg.conf or any *.conf file in .../xorg.conf.d/

I installed the ddx driver and now startx works...the modsetting driver doesnt work with xorg..

EDIT: I have a question...

If i set VIDEO_CARDS="intel i915" in /etc/portage/make.conf,
Which intel driver is pulled from x11-base/xorg-driver ?

If i set VIDEO_CARDS="intel i965" in /etc/portage/make.conf,
Which intel driver is pulled from x11-base/xorg-driver ?

Which one of the above settings pulls the xf86-video-intel ?
Does xorg-drivers package even contain the xf86-video-intel driver?
The guide says choosing i965 omits xf86-video-intel..Am i getting this right ?

I am asking because i set the intel and i965 variables in make.conf..but startx returned errors and I had to manually install the xf86-video-intel driver to make xorg+dwm work...
