Widescreen monitor won't configure to a wide screen
by MHR 31 Jul '08

31 Jul '08

I just put a 1680x1050 LCD monitor on my home system, and I went into system-config-display to configure it as such, and it just won't take. I had to tweak some of the settings by hand, but when I log out, I get the wide screen for both the Nvidia driver splash screen and the login screen. But, when I log in, It jumps back to 1280x1024 and refuses to run in wide screen mode. Here's the xorg.conf (even when I'm logged in and the screen is only 1280x1024): # Xorg configuration created by system-config-display Section "ServerLayout" Identifier "single head configuration" Screen 0 "Screen0" 0 0 InputDevice "Keyboard0" "CoreKeyboard" EndSection Section "InputDevice" Identifier "Keyboard0" Driver "kbd" Option "XkbModel" "pc105" Option "XkbLayout" "us" EndSection Section "Monitor" ### Comment all HorizSync and VertSync values to use DDC: # HorizSync 31.5 - 65.5 # VertRefresh 56.0 - 65.0 # Option "dpms" Identifier "Monitor0" ModelName "LCD Panel 1680x1050" ### Comment all HorizSync and VertSync values to use DDC: HorizSync 30.0 - 82.0 VertRefresh 56.0 - 76.0 EndSection Section "Device" Identifier "Videocard0" Driver "nvidia" EndSection Section "Screen" Identifier "Screen0" Device "Videocard0" Monitor "Monitor0" DefaultDepth 24 Option "NoRenderExtension" "False" Option "AllowGLXWithComposite" "True" Option "RandRRotation" "True" Option "XvmcUsesTextures" "True" Option "AddARGBGLXVisuals" "True" Option "TripleBuffer" "True" Option "DamageEvents" "True" SubSection "Display" # Modes "1680x1050" "1600x1024" "1440x900" "1400x1050" "1280x1024" "1280x960" "1280x800" "1152x864" "1024x768" "800x600" "640x480" Viewport 0 0 Depth 24 Modes "1680x1050" "1600x1200" "1600x1024" "1440x900" "1400x1050" "1280x1024" "1280x960" "1280x800" "1152x864" "1024x768" "800x600" "640x480" EndSubSection EndSection The commented out Horix and Vert syncs are for my old monitor (a 17" non-ws), and the new ones are from the manual for the new screen. I tried with these commented out, but it still would not work. One thing I noticed is that when the gdm starts up, it goes from "auto adjust" (wide screen) to "analog-d" (non-ws) - dunno what that means. Any suggestions? It's really annoying to have a wide screen and not be able to use it.... Thanks. mhr What am I missing?

That worked. It was at init 3, and init 5 gave me the behaviour I wanted. === Al

rpm dependency question
by Mark Belanger 31 Jul '08

31 Jul '08

I have an rpm I've created that has a dependency on a library provided by a third party. This dependency is not specified anywhere in my spec file yet the package seems to know about when I run: # rpm -qip --requires MyPackage.rpm The third party rpm is installed and uninstalled via a vendor-supplied script so that they can prompt you to accept licenses and so on. Problem is, the vendor supplied un-install script fails to un-install because of the dependency MyPackage has on one of it's libraries. Is there a way to build my package so that it has no knowledge of external dependencies? My other option is to alter the vendor supplied uninstall script so that it does rpm -e --nodeps. I'd very much prefer to not mess with the vendor supplied scripts. I guess as a related question, how does my rpm know about external dependencies? Is rpmbuild doing some analysis of it's content via ldd or something? -Mark -- Mark Belanger LTX Corporation

Mounting File Share Using CIFS ?'s
by TechGuy 31 Jul '08

31 Jul '08

I have been trying to mount a windows file share so I can use it for remote storage particularly for my Deki Wiki attachments. Anyway, I seem to have a mount established by doing the following. 1. Added following line to /etc/fstab //fs01/wikidata /var/www/dekiwiki/attachments cifs user,uid=500,rw,suid,username=wikisvcacct,password=testpwd,domain=corporate 2. Then ran following command to mount it. mount //fs01/wikidata 3. Then ran following command to confirm mount. df Output of 'df': //fs01/wikidata 1821803064 1435671544 386131520 79% /var/www/dekiwiki/attachments This would appear to indicate the mount was successful correct? If I understand this whole thing, if i change directory to /var/www/dekiwiki/attachments would I then be using or looking at //fs01/wikidata ? Or am I still looking at the local file system? Or does it depend on the user? Since I set this up for the dekiwiki user with uid=500, would I logged in as root be able to access this mount or do I need to add another line in the /etc/fstab for root? Thanks!

Will CentOS 6's upstream be based on Fedora 10?
by Kanwar Ranbir Sandhu 30 Jul '08

30 Jul '08

Hi All, The subject says it all. I'm asking because I've found Fedora 9 to be buggy as hell - it is one of the worst Fedora releases I've ever used (and I've been using it since Fedora Core 1). I'm putting up with it for my work laptop, but it's not fun. :( My main home machine is still on Fedora Core 6 and will stay there until CentOS 6 comes out. I don't want to use CentOS 5 because it's upstream is based on Fedora Core 6, and I want something new! When CentOS 6 hits, I will be using it for my work laptop. I might just keep Fedora for home my machine. I haven't decided yet if I want to move up to Fedora 10 or CentOS 6. Regards, Ranbir -- Kanwar Ranbir Sandhu Linux 2.6.22.14-72.fc6 i686 GNU/Linux 10:30:46 up 20 days, 11:40, 1 user, load average: 0.77, 0.79, 0.72

Wiki updates needed for rpmrepo.org when it's up & running
by Lanny Marcus 30 Jul '08

30 Jul '08

When rpmrepo.org is up and running properly, there are 2 or 3 Wiki pages that need to be updated. I wiped the HD on my daughter's box and am trying to install multimedia on it again. The change from RPMForge to rpmrepo.org requires some minor updates to several Wiki pages. http://wiki.centos.org/TipsAndTricks/MultimediaOnCentOS http://wiki.centos.org/AdditionalResources/Repositories/RPMForge http://wiki.centos.org/AdditionalResources/Repositories IMHO, the stuff on the Wiki is a wonderful asset. Especially, for those of us who are Newbies. Much appreciated!

usb to usb comm ports - possible? how?
by James B. Byrne 30 Jul '08

30 Jul '08

I have an i686 mono core system configured as a CentOS-5.2 server. It has one DB9P RS-232 serial connector and six USB connectors. The DB9p is configuered as STTY0 for the attached MultiTec MT5638ZBA fax modem. I would very much like to connect my MS WindowsXPpro laptop, which only has USB connectors, to this server via telnet or ssh over a direct connection. Is there a way to connect / configure a comm port to a raw USB port in windows / centos and to use a direct cable connection between the two? Or, is a usb to serial converter device required at both ends? I expect to use either puTTY or hyperterm as the windows client. What I need to know is: Is this is even possible? How do you configure the tty ports on CentOS for this to work? How do you configure the comm port on MS-WinXPpro? What cable does one require? I have never had this problem before since all our hosts have previously come equipped with two serial ports. However, the next generation machines apparently have no RS-232 serial ports at all, just six usb ports. So, this problem might as well be faced now as later, when it is unavoidable.

Missing dependencies
by Guy Boisvert 30 Jul '08

30 Jul '08

Hi! I have a new shiny CentOS 5.2 server freshly installed. I wanted to install VMWare Server but the installer wants to compile a module. I thought, no problem: Let's install compiler and libraries. So i did: yum groupinstall "Development Libraries" "Development Tools" But i end up with: ================== --> Processing Dependency: libsqlite3.so.0 for package: rpm-devel --> Finished Dependency Resolution Error: Missing Dependency: libidn = 0.4.6-1.2.el5.rf is needed by package libidn-devel Error: Missing Dependency: libsqlite3.so.0 is needed by package rpm-devel Error: Missing Dependency: libidn.so.11 is needed by package curl Error: Missing Dependency: libsqlite.so.0()(64bit) is needed by package sqlite-devel Error: Missing Dependency: sqlite = 2.8.17-1.el5.rf is needed by package sqlite-devel Error: Missing Dependency: libsqlite3.so.0 is needed by package rpm-libs What's really missing and why it doesn't seem to be in the repo? Thanks! Guy Boisvert, ing. IngTegration inc.

slow NFS speed
by Mag Gam 30 Jul '08

30 Jul '08

We upgraded from a 10/100Mbs to a 2 100/1000 bonding. We notice the speeds of NFS to be around 70-80Mb/sec. Which is slow, especially with bonding. I was wondering if we need to tune anything special with the Network and NFS. Does anyone have any experience with this? TIA
