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. -- John Carr (jfc@athena.mit.edu)
