Display problem

Hi guys,

        Just shifted to opensuse 12.2 few days back and My problem is I have Installed xf86-video-modesetting driver to solve the resolution problem after installing that driver when I log in  a black screen along  with mouse pointer appears.if I press Ctrl+Alt+F2 and Ctrl+Alt+F7 then it works fine what should I do if I have to get display directly after logging in.

Thanks in advance.

I can’t guarantee a solution here, as I don’t have this hardware, but after googling around (the same as you might need to to), I have read of similar behaviour discussed - for example

12.04 - How can I avoid the black screen on boot with GMA500 graphics? - Ask Ubuntu

with suggestions to examine /etc/default/grub, and find the line

GRUB_CMDLINE_LINUX=""

Edit it

GRUB_CMDLINE_LINUX="console=tty1"

Save the changes. With openSUSE, you update grub2 with

grub2-mkconfig -o /boot/*grub2*/grub.cfg

and reboot.

No promises that this will work for you though. You may need to search for a solution yourself.

You may need to add ‘console=tty1’ to the ‘GRUB_CMDLINE_LINUX_DEFAULT=…’ entry instead. (Leave the existing options as they are.) YMMV

FWIW, other information I found and read
Peppermint | Linux OS Community Forum • View topic - (SOLVED) Blank black screen after boot
Ubuntu 12.04 gma500 (poulsbo) boot options | Shadows of epiphany

That’s as much as I can offer. Good luck.

I have tried adding console=tty1 to both GRUB_CMDLINE_LINUX_DEFAULT and GRUB_CMDLINE_LINUX separately but didn’t work for me

Given xf86-video-modesetting has a rather limited set of usage scenarios, it begs the question why are you attempting to use it? You did not describe your configuration, and only that you are attempting to “solve the resolution problem”. I’m not sure what “the” resolution problem is, though I have no doubt that you may be experiencing “a” resolution problem lol!

In any regard, (given the nature of the video-modesetting driver) I highly suspect that you are misusing it or going about things the wrong way to try to solve “a” problem.

Please provide more details.

Thanks for the reply.
I am using Intel D2500HN board with g3600 graphics controller.Last time our friends told me to install modesetting driver and after installing this driver it is able to detect monitors but it flickers(small horizontal lines when I roll cursor over an icon or if I type anything in the terminal) and the above mentioned problem occurs.

@Tyler_K: For the background on this, refer to the following thread

@nishanth9042: I think this is due to limitations with your hardware and the drivers concerned. I’m not sure much more can be done.

Ahh, thanks – I had previously only read the last 3 or 4 posts of that thread and saw that it was “problem solved” so read no further.

Ahh, I see. Cedar Trail Platform (Intel Atom/Cedarview & GMA 3600/PowerPV SGX545).

I know little about the PowerVR stuff … except to avoid it if possible (to minimize frustration). … I do see that there is no OSS KMS supporting DDX available, so yeah, this is one of the few cases where the video-modesetting driver could be handy

Last time our friends told me to install modesetting driver
okay

and after installing this driver it is able to detect monitors but it flickers(small horizontal lines when I roll cursor over an icon or if I type anything in the terminal)
Yes, you won’t see good 2D performance because it (the video-modesetting driver) does not provide any acceleration … the other choice, fbdev, doesn’t either, and worse, you lose out on the KMS …

and the above mentioned problem occurs: …“after installing that drive when I log in a black screen along with mouse pointer appears.if I press Ctrl+Alt+F2 and Ctrl+Alt+F7 then it works fine what should I do if I have to get display directly after logging in.”
Ahh, I see. Off hand I’m not sure about that.

However, if you are not aware, you might want to look into the recent binary drivers for the chipset;. See:
Ubuntu 12.04 Driver for Intel Cedarview (Atom-(N)2000- und (D)2000-Serie) | Online @ Hamburg

That may provide you with a much more pleasant experience then the limited capabilities you are currently getting.
