Appendix A Changing the Console Resolution 31
Troubleshooting
TABLE A-2
Troubleshooting
Problem Solution
Used the method
described in this
appendix to configure
the console resolution,
but the card still
defaults to something
other than the
resolution specified. A priority scheme is used to determine the boot console
resolution. The PGX32 firmware checks the various methods in
the order of priority that is discussed below. If it finds the
resolution from the current method, it uses it; otherwise, it goes
down the priority list to find the resolution information. Finally, if
there is no resolution information, it uses the default resolution.
The resolution-setting methods are enumerated in the order of
decreasing priority:
1. DDC2B/EDID auto-detect
2.
output-device
Method
3. Video-Timing Method
4. Video-Mode Method
5. Default resolution for the card
The chosen resolution
on the PGX32 is
compatible with my
monitor, but there is
still no video. Early versions of the PGX32 card require an adapter in order to
support composite sync.
Applications using
PHIGS, XGL or PEX
can cause the window
system to crash on a
PGX32 frame buffer. This is caused by bugs in the PEX library and is not specific to the
PGX32 frame buffer. The workaround is to set the
XGLNOPEX
variable before executing PHIGS, PEX or XGL applications. To set
the variable, type:
%
setenv XGLNOPEX TRUE

installed in order to run ShowMeTV™.
