Original-subject: Xibm fixes for RT(AOS) and PS/2
Reposted-by: emv@msen.com (Edward Vielmetti, MSEN)
export.lcs.mit.edu:~ftp/contrib/Xibm-athena.tar.Z contains a collection of
fixes we have made to the Xibm server for the RT running BSD and PS/2
running AIX 1.2. I've had enough requests for the changes that I've decided
to put them on export. Some of these have appeared before (I placed a
smaller collection of changes on expo last year). The changes for PS/2
include fixes for the ibm8514 code from a source I don't remember.
Partial list of changes:
megapel cursor code improved
megapel poly point code used to hang for large requests
megapel GC clip region was calculated incorrectly when a
GC was shared by several windows (this affected Andrew
messages)
ppc code to draw small rectangles was incorrect (rectangles
smaller than line width were drawn very large); this affected
megapel and 8514
8514 had a number of bugs drawing proportionally spaced text;
some of these have been fixed
RT: try to open mouse again if first open fails (there is a
kernel or hardware bug on our RTs which somestimes causes the
mouse open to fail the first time)
AIX: allow ttyname() to return NULL; fix bug which made uwm
crash the server
The changes are in the form of a compressed tar file with replacements for
the files that have changed (270 KB total).
We are running these changes on RTs with megapel and apa16 displays, and on
PS/2s with 8514 (color and greyscale) and VGA displays. There are still
some bugs in the 8514 code.
