1400x1050 on Intel 915GM
Problem: Native Resolution of Internal LCD not automatically supported
If your laptop panel has an unusual native resolution such as 1400x1050, and the native resolution is not automatically supported, and if your video adapter is something like Intel 915GM you may need to download and install the program 915resolution, read the documentation and add a line into /etc/rc.local such as:
915resolution 3c 1400 1050
and then configure /etc/X11/xorg.conf with care... see x.org FAQVideoModes.
Problem: System resumes from suspend but video is not working
First try the single change:
- To /usr/sbin/pm-suspend, following the line echo -n "mem" > /sys/power/state, add the line: 915resolution 3c 1400 1050
In Fedora Core 5, /usr/sbin/pm-suspend is the suspend script called by the OS to suspend the machine. If you are using a different distribution you may have to find the relevant files.
If that does not solve the problem, try the following.
- Check BIOS settings that refer to power and suspend mode.
- To /boot/grub/grub.conf add to the relevant lines beginning "kernel" the following option: acpi_sleep=s3_bios
