grub.conf and /proc/cmdline
by Jerry Geis 05 Mar '10

05 Mar '10

I have a grub.conf (below) with pci=nomsi, also /proc/cmdline and dmesg | more do not show the pci=nomsi. How can this be? there are no strange characters after quiet and before pci=nomsi. It was edited with vi. What can I do to get this parameter in my kernel boot line.

ImageMagick Bug
by Michael A. Peters 05 Mar '10

05 Mar '10

Hello, I am experience a segfault while trying to use convert between svg and png. I suspect that the bug I am experiencing is identical to this one: https://bugzilla.redhat.com/show_bug.cgi?id=472253 I can try the suggested patch myself, but is this the kind of thing that maybe could be patched in CentOS plus repository until RHEL has an approved patch? The report looks several years old yet there still isn't one, which isn't a good sign. The issue I'm dealing with, on my web site I am moving a lot of the currently gd generated dynamic png images to svg but since not all browsers support svg, I need to convert from svg to png for a fallback. I suspect I'm not the only one who wants to do this sort of thing, so segfault in convert from svg to gif/png is really something that probably should have a fix readily available. I'm running CentOS 5.x

Hylafax does not pick up.
by James B. Byrne 04 Mar '10

04 Mar '10

We run the distro HylaFax on a CentOS-5.4 host. On infrequent occasions we notice that the server will not pick up an incoming call. It reports listening to modem rings. Now, it seems to me that picking up the call should be under the control of the modem but I notice that there exists a setting in Hylafax for the number of rings before picking up. The default value for this is 0 (zero) but we have it set to 1 (one). Because of this option I am not sure whether there is something wrong with the server or with the modem. Has anyone else experienced this problem and discovered its cause? -- *** E-Mail is NOT a SECURE channel *** James B.

Permissions problem

What am I doing wrong here? I need to be able to write to /var/cvs. This used to work before I moved these groups into an LDAP directory instead of /etc/group: [scarolan@watcher:/var/cvs]$ touch test.txt touch: cannot touch `test.txt': Permission denied [scarolan@watcher:/var/cvs]$ ls -ld drwxrwsr-x 4 cvs cvsgrp 4096 May 18 2008 .

Its just that disks with 100s or 1000s of gigabytes take a long long time to fully write. DBAN's default erase sequence is excessive for modern disks. the old DOD erase sequences were devised for media that used simple NRZ type encodings, with RLL encoding methods used by modern disks, they don't make any sense at all. all you really need is to write the disk with all 1s, then all 0s, and its about as good as it will get, not even CSI:Miami will find any actual data on it (of course, if the script writers need to, they'll invent data out of thin air).

[Possibly OT] rpm conflicts has me confused
by Bob Beers 04 Mar '10

04 Mar '10

Hi list, I can install the default ppp-2.4.4-2, but when I try to install an rpm I built from Sangoma's ppp-2.4.4.5 (using checkinstall-1.6.1) I get this error: # rpm -ivh ppp.2.4.4.5-1.eai.i386.rpm error: Failed dependencies: ppp < 2.4.3-3 conflicts with kernel-2.6.18-162.2.1.el5.i686 Isn't 2.4.4.5 > 2.4.3-3 ??? trying this: yum localinstall ppp.2.4.4.5-1.eai.i386.rpm --nogpgcheck gives some advice: You could try using --skip-broken to work around the problem You could try running: package-cleanup --problems package-cleanup --dupes rpm -Va --nofiles --nodigest and I tried each of those, but no joy. Is this an rpm bug, a checkinstall bug, or PEBKAC (problem exists between keyboard and chair)? thanks, -Bob Beers

X server crashes when I fire up "Display" or "Screen Resolution" control panels
by Aleksey Tsalolikhin 04 Mar '10

04 Mar '10

Hi. I've just installed CentOS 5.4 on my IBM T61 laptop. By default, I get the same image (duplicate screens) on the laptop's LCD and on the external monitor; I want to set up separate screens but my X server crashes when I start "Display" or "Screen Resolution" control panels or press Function-F7 which is supposed to bring up the single screen/ multiple screens selection menu. I am including my Xorg.log, could somebody help me sort this out, please, or at least point me in the right direction? I do see this: (WW) intel: No matching Device section for instance (BusID PCI:0:2:1) found (--) PCI:*(0:2:0) Intel Corporation unknown chipset (0x2a02) rev 12, Mem @ 0xf8100000/20, 0xe0000000/28, I/O @ 0x1800/3 (--) PCI: (0:2:1) Intel Corporation unknown chipset (0x2a03) rev 12, Mem @ 0xf8200000/20 Do I need a special video driver? I checked http://www.linlap.com/wiki/ibm-lenovo+thinkpad+t61 which says this laptop should work OK with recent Linux distros; and I tried the xorg.conf mod in http://www.thinkwiki.org/wiki/Installing_Fedora_8_on_a_T61#Graphics but X crashes when I run xrandr. I went on the vendor website but there is no driver available - they did have an NVIDIA driver for SUSE, but my laptop does not have an NVIDIA device and I am running CentOS, not SUSE! Help? Best, -at
