more on identifying the system a program is running on...

by Fred Smith

I asked recently about using /etc/redhat-release and got some useful answers. My thanks to all who replied. Now a slight variant: Can anyone suggest some resource that a PROGRAM (compiled C program) can examine while running to find out what platform it is runninng on ? Things that come to mind include: 1. output of uname to see if the kernel version contains "elX" where X is a digit, such as el4, el5, etc., identifying RHEL-4, RHEL-5, etc. 2. do the same thing by exmining the filename of the kernel (if I knew how to find the file for the currently running kernel, that is. can anyone suggest any other checks I could do? Thanks again! -- ---- Fred Smith -- fredex(a)fcshome.stoneham.ma.us ----------------------------- The Lord detests the way of the wicked but he loves those who pursue righteousness. ----------------------------- Proverbs 15:9 (niv) -----------------------------

LTSP and DRI2, Fedora 12 and glxgears

by Norman Gaywood

I have a fully updated Fedora 12 ltsp-server-5.1.95-1.fc12.i686 setup connecting to a fully updated Fedora 12 server. A user logs in from a thin client and trys to run glxgears: $ glxgears X Error of failed request: BadRequest (invalid request code or no such operation) Major opcode of failed request: 136 (DRI2) Minor opcode of failed request: 1 (DRI2Connect) Serial number of failed request: 18 Current serial number in output stream: 18 Any suggestions on how to fix this? I've been googling for awhile on this problem and found others with the same issue but never a clear solution. I'd even be interested to hear someone say "It works for me". Xorg.1.log from one of the thin clients can been seen here: http://fpaste.org/m2vV/ Following is the output from xdyinfo. $ xdpyinfo name of display: 129.180.101.50:1.0 version number: 11.0 vendor

To solve this problem Selecting the correct In Solaris the getent utility provides a generic retrieval interface to search several name service databases in the order in which they are specified in/etc/nsswitch.conf.
