Resolution problems

I have recently installed Slackware on my HP Pavilion 6500 laptop and I have been having problems with my resolution. I am attaching a picture to show you what it is doing.

I've tried using xorgsetup because it does nothing.

Help!

Please post some details about the resolution range available on the laptop. It would help to solve the issue. It looks like the actual desktop is bigger than your monitors resolution so have you you tried moving around . Just push against the edges left and right, top and bottom with your mouse.

I've looked and found pretty much nothing on the resolution. Here is the pdf for my laptop and another website about my laptop.

I've also tried to manipulate the screen but get nothing. I've tried xorgsetup and can't get it to fix it.

So this happens when you try to install slackware, during the installer ? That's what it looks like, but I'd like to be sure.

I would check the BIOS settings. I know on one of my desktop computers with Intel graphics, strange things may happen if I set the memory usage for the Intel graphics chipset to maximum in the BIOS. Other settings work ok.

No, this is after the fact. When I boot up Slackware and the resolution screws up when it seems the graphic hardware/software is loaded but I'm not sure.

I realize that maybe you will be unable to do this as the screen is gibbled.

That laptop screen resolution is 1280 by 800.

So can you open system settings and click on monitor and use the drop down menu to select resolution?

I assume you are using KDE but since you haven't said please enlighten us.

I suggest running xwmconfig and start the GUI setup process again.

it looks like it is still in terminal mode and not in X yet, if that is the case you need to edit either grub.cfg or lilo.conf and adjust the video modes...if thats the case let me know i'll try to walk you through it

When you the boot the laptop, try adding 'video=1280x800' as a kernel boot option. (If you are using lilo as the boot manager, hit the Tab key).
If this fixes the problem, you can make this permanent by adding the string to the 'append' line in /etc/lilo.conf and rerunning lilo.

For X, if you look in /etc/X11 there will be a file named xorg.conf this file contains all the information your system has concerning the video. Mine is named xorg.conf.vesa, yours will undoubtedly be different. Just find the file, it is plain text, and post it so we can see what you have configured and maybe come up with a good solution to help you.

A sudden change in resolution during boot usually means that it switches to framebuffer or tries to.

Set:

Code:

vga=normal

in '/etc/lilo.conf' and run 'lilo' as root.

What graphics card and drivers are you using ?

The OPs original post links to a picture that seems to show displacement in the console screen after the boot has been completed. The information in the supplied PDF says:

Looks like a candidate for Bumblebee, but clean console screen will help.

Does your laptop have the Intel GPU? I've seen lots of problems with new Linux kernels and older Intel Graphics hardware. My Macbook circa 2007 doesn't have the same issue, but things like 3D acceleration suck big-time on Slackware-13.37. Older versions of Slackware work fine on it but lack a few other nice-to-have features. I've seen similar video corruption in X on another Intel box (this one a desktop) from that era.

If you don't mind a little testing via re-install, see if you can throw Slackware 13.0 on there and let us know if the problem persists.

This is all of course assuming there's no physical problem with your GPU.

If you load X, does the problem go away? If so, open a console in X and give us the output of lspci -v.
