Dual video card, 1 monitor each (ref dual head) CentoS4.6 xorg does only 1 head
by William L. Maltby 09 Aug '08

09 Aug '08

I need to start running a dual head on one of my machines. Eventual target is CentOS 5.x. Decided to test first on my 4.6 setup (eventually it will achieve 5.x). Both machines are fully up to date. The test machine is 4.6, 2 radeon video cards. Searched the web, CentOS site, even bugzilla. This bugzilla entry from a 4.2 system), http://bugs.centos.org/view.php?id=1875 had only a WFM response. I've attached a gzipped text file of pertinent information. Briefly, kudzu did the right thing when I installed the second card. System-config-display also behaved correctly. X start ok, but will only use one head at a time. Adding a second "BusID" so that both cards are explicitly addressed didn't help. When the 2 "BusID" entries are switched, the active screen doesn't move (it's always "Screen0") and the ignored screen ("Screen1") remains the same. The monitor attached to the video card for "Screen0" becomes the active one. Q1: Anyone have a two video card CentOS 4.6 setup working? Q2: Is it working in CentOS 5? Q3: Anyone see something I'm doing wrong? Suggestions? TIA, -- Bill

Good reference for dkms?
by MHR 09 Aug '08

09 Aug '08

I've just built the nvidia driver for my home machine for the third time and I'd like to put it into a dkms format, but I'm not entirely clear on what goes where to make this work. I googled for a good primer on dkms, but what I'm finding is essentially equivalent to the man page, which, like most Unix/Linux man pages, doesn't really tell you "how to do this from scratch." I'm using nvidia's latest driver, r. 173.14.09, which seems to be more recent than the last one I have from rpmforge (1.0.9755, IIRC), although I'm not sure I really need anything other than the rpmforge version. Should I 1) revert to the rpmforge version and re-add it back into the dkms tree? IIRC, this wasn't that hard to do, 'cuz it was meant to be done in the first place. 2) try to bungle my way through with the newest one from nvidia? Or is there a really good primer on dkms that tells what to put where and how to create a proper dkms.conf file (and where)? Thanks. mhr

MRTG Problem - no traffic recorded
by Morten Nilsen 09 Aug '08

09 Aug '08

Hi all, I've just recently replaced my old firewall with a new one, running CentOS 5.. Yesterday, I decided to get MRTG up and running again, so I entered sections like this into the mrtg.conf file: Title[vlan10]: Bandwidth usage on tenchi.4th-age.com (Internet) PageTop[vlan10]: <H1>Traffic stats on VLAN 10 (Internet)</H1> Target[vlan10]: `ifconfig vlan10 | /usr/bin/awk '/bytes/{ gsub(/:/, " "); print $3 "\n" $8}'` MaxBytes[vlan10]: 12500000 Options[vlan10]: noinfo, growright, bits WithPeak[vlan10]: wmy The Target is all on one line in the file. This config worked fine on my old firewall, but on the new, I get this in the log files: [root@tenchi mrtg]# head /var/lib/mrtg/vlan10.log 1218175802 -1 -1 1218175802 3 3 3 3 1218175501 3 3 3 3 1218175500 3 3 3 3 When testing, I ran the mrtg command, precisely as it is written in /etc/cron.d/mrtg, and that placed real values where now it says -1, but as soon as the cron job ran, the values became -1 again. I hope someone can shed some light on this problem.. -- Cheers, Morten

Stopping setroubleshootd failed
by Lanny Marcus 08 Aug '08

08 Aug '08

This is probably a known issue, but just in case. On my Desktop, I am running SELinux in Permissive mode. When I restart the system, or shut it down, I notice this message: "Stopping setroubleshootd failed". Notice at the end of the dmseg output below, regarding SELinux, there are three (3) identical lines. I don't know if that is normal or not.

Package request: php, pear: spreadsheet::excel::writer
by Morten Nilsen 08 Aug '08

08 Aug '08

Hello, I am currently using this PEAR package to generate .xls documents in PHP; http://pear.php.net/package/Spreadsheet_Excel_Writer It would be very much appreciated if someone could add it to the repository, as it is always to prefer rpm packages over manually installed ones. -- Cheers, Morten

Command line partition manipulation
by Plant, Dean 08 Aug '08

08 Aug '08

I want to write a script to automatically modify the partition table I am starting with 3 partitions like this # parted /dev/sda print Model: VMware, VMware Virtual S (scsi) Disk /dev/sda: 10.7GB Sector size (logical/physical): 512B/512B Partition Table: msdos Number Start End Size Type File system Flags 1 32.3kB 107MB 107MB primary ext3 boot 2 107MB 4828MB 4721MB primary ext3 3 4828MB 9023MB 4195MB primary lvm And I want to remove partitions 2 & 3 and recreate 2 from the end of 1 to the end of the disk i.e. all the free space. Removing 2 and 3 is easy. # parted /dev/sda rm 3 # parted /dev/sda rm 2 # parted /dev/sda print Model: VMware, VMware Virtual S (scsi) Disk /dev/sda: 10.7GB Sector size (logical/physical): 512B/512B Partition Table: msdos Number Start End Size Type File system Flags 1 32.3kB 107MB 107MB primary ext3 boot Is there a way to use a non-interactive command to create the new 2nd partition in the free space? Thanks Dean
