28 HP-UX Configuration
Description
The PA-RISC server systems do not
support VGA as a console.
After booting CDE does not come up
on the HP PCI AMD Radeon 7000
Graphics Adapter display.
3D applications fail to run or run very
slowly.
The dtlogin process is running but
the monitor is blank or corrupted.
Flashes, dots, or other random
artifacts are present on the monitor.
Solution
Serial console must be used.
CDE starts at run level 3. Check your
run level with who -r command.
Change it with the command
/sbin/init 3.
Check your /etc/dt/config/
Xservers file, if it exists. There
should be a line at the bottom such as
* Local@console
/usr/bin/X11/X :0 that is not
commented out. This line might get
commented out by the system if there
is no mouse or graphics.
Is a keyboard and mouse attached?
The Xserver will not start unless a
mouse and keyboard are attached.
Is the Xserver configured with the
correct /dev/gvid devices?
Accelerated 3D is not supported on the
HP PCI AMD Radeon 7000 Graphics
Adapter. Some 3D applications may
run through emulation mode at greatly
reduced performance.
Is the monitor connected to the correct
display connection on the HP PCI
AMD Radeon 7000 Graphics Adapter?
Does the monitor support the
resolution and refresh rate that the
Xserver is running at?
At high resolutions and refresh rates
this type of problem can occur on some
monitors.
Use only the cables provided with the
monitors.
Lower the refresh rate and/or
resolution.
