I'm new to Linux and Ubuntu and trying it out but installing 10.10 via Wubi on to my old Samsung V25 laptop.
For the larger part, the system seems to be working fine, apart from one key point, its internal monitor is not functional, only output to an external monitor works.
During install and the GUI section of setup, (where the slideshow is displayed, after the Windows part), displayed correctly on the internal monitor, however, after the first reboot, as soon as the Splash screen displays on my external monitor, the internal one shuts off completely. Not blank, it appears entirely turned off.
The graphics card is reported by lspci -nn as an 'Intel Corporation 82845/G/GL[Brookdale-G]/GE Chipset Integrated Graphics Device [8086:2562] (rev 03)'.
With some help of friends, I've run xrandr but it reports LVDS1, the laptop screen as 'Unknown Connection'. Trying to force display through it at a known safe resolution causes the error: "cannot find crtc for output LVDS1"
How can I fix this so I can use the laptop with just its internal monitor rather than having to hook it up to another screen?
Update: Having done further searching online, I have now got the system to the point of being able to boot to text mode at 800x600 and, if an external monitor is connected, boot in to graphics mode. If the external monitor is not connected, graphics fails to start but I can at least Ctrl+Alt+F1 to the terminal. To do this, I added
i915.modeset=0 xforcevesa to the boot instruction. Along with setting
GRUB_GFXPAYLOAD to 800x600. And set the Driver in the Device section of xorg.conf to
Now my only requirement is setting the laptop to boot with graphics mode without needing an external monitor connected.
