Installing Fedora Core 5
- Aside from the following PCM issue, the configuration challenges are the routine issues of deciding on your partitioning and deciding which packages to include.
- After the first reboot, the installation process asks your choice for default PCM device. The two options are: Intel ICH - Intel ICH6 / Intel ICH - IEC958.
I have no idea which to choose, and don't know if the choice is one that can easily be changed later. There is no obvious external digital output, so I choose the first and hope for the best.
- After the initial install, in order to get the system up to date, you will have to TWICE as root issue the command:
# yum update
and then wait a long time for each update to complete, as there may be around 100 packages updated each time.
- see 1400x1050 on Intel 915GM. Download and install 915resolution and add to /etc/rc.local the line: 915resolution 3c 1400 1050
- Getting suspend and resume to work:
- Check BIOS setting: Power On; Press F1 to enter BIOS settings. Check that the value for Config -> Power -> "Allow suspend mode on legacy OS" is: Enabled. On my system, this BIOS option did not affect FC4; however FC5 would not resume properly if the setting was Disabled.
- To /boot/grub/grub.conf add to the relevant lines beginning "kernel" the following option: acpi_sleep=s3_bios
- To /usr/sbin/pm-suspend, following the line echo -n "mem" > /sys/power/state, add the line: 915resolution 3c 1400 1050
- Controlling cpuspeed: My preference is to edit /etc/cpuspeed.conf, commenting out -n and adding OPTS="$OPTS -s 0 -i 1 -r -p 45 50". My CPU use patterns are high spikes with low idles so this provides maximum responsiveness but generally keeps the CPU at (ambient temperature + 20 degrees Celsius).
Installing Fedora 7
- To avoid problems when the computer is turned on with external monitor connected:
- BIOS setting: Configure Display: Startup on Internal LCD (not Both)
- To get the native 1400x1050 internal LCD resolution:
- Install 915resolution
- Edit /etc/sysconfig/915resolution to have the line
RESOLUTION="3c 1400 1050"
- To get the internal display to resume properly after suspend (instead of the ghostly glow)
- Make an executable file /etc/pm/config.d/r52.cfg with
- Edit xorg.conf to enable different desktop on external 1280x1024 monitor: to Section "Screen", Identifier "Screen0", Subsection "Display" add
Virtual 2680 1050
- script to run when in X:
#!/bin/sh xrandr --output VGA --right-of LVDS --off >/dev/null 2>&1 || : xrandr -s 1400x1050 >/dev/null 2>&1 || : if xrandr | grep "VGA connected"; then xrandr --output VGA --right-of LVDS --auto fi
