Fedora 11 GDM - unwanted list of all local users and impossible to customize?
by jaivuk 31 May '10

31 May '10

Hello guys, I did not use gdm for some time and now I'm not happy how it looks in Fedora 11. First of all - the list of local users is unacceptable from security reasons. Even if it supports such "an " option - how it can be the default one?! Second problem I have is shutdown button (and possibly restart as well) - when you click on shutdown button by mistake, system will shut - there is no confirmation dialog. I also tried to find some ways how to customize gdm in Fedora 11 but I did not find any usable guide. Can anybody please advise me how can I have prompt asking for username only (showing last logged user at maximum) and not displaying the list of all local users? Also can I somehow add confirmation or remove shutdown restart buttons from gdm screen? Or can you please advise any alternative to gdm? Thank you very much, Jan

Rendering chart from bootchart
by Suvayu Ali 21 May '10

21 May '10

Hi everyone, I have been seeing very long boot times for the last few months so I ran bootchart. But I can't render the chart after booting. The web interface seems to be down. And the java application supplied with bootchart generates the following error. > $ java -jar /usr/share/java/bootchart.jar > Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/commons/cli/ParseException > Caused by: java.lang.ClassNotFoundException: org.apache.commons.cli.ParseException > at java.net.URLClassLoader$1.run(URLClassLoader.java:217) > at java.security.AccessController.doPrivileged(Native Method) > at java.net.URLClassLoader.findClass(URLClassLoader.java:205) > at java.lang.ClassLoader.loadClass(ClassLoader.java:319) > at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:294) > at java.lang.ClassLoader.loadClass(ClassLoader.java:264) > at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:332) > Could not find the main class: org.bootchart.Main.

Installing F12 on Mactel
by Leon Stringer 12 Apr '10

12 Apr '10

Hi, I've tried to install F12 on my Core 2 Duo iMac. The installation seemed to go okay but there's no sign of Fedora when I boot. I hold down the <Option> key and just get the MacOS partition. Is there a trick to this? Thanks in advance, Leon...

Critical temperature reached, shutting down
by Steve Malenfant 29 Mar '10

29 Mar '10

I have an ECS board which triggers these Critical temperature alarm and them my system shuts down. This happens only in "yum update" but doesn't on video playback for hours. Jan 14 14:06:19 localhost kernel: Critical temperature reached (127 C), shutting down. Jan 14 14:06:19 localhost kernel: Critical temperature reached (127 C), shutting down. The problem I have is that the CPU temp stays about 40C when this happens (using sensors) and can't find any temperature that goes higher in the sensors data. Seems like a ACPI problem but the kernel log message has no details on which sensors is at 127 C. Is there a way to tell the kernel to be a bit more verbose on these? Thanks.

kernel module
by Luca 12 Mar '10

12 Mar '10

Hi all, I created a kernel module which can be passed some command line arguments (I tried that with insmod and it works). Now I would like, when I start the kernel with grub, to have this module loaded at boot time so I can pass, at boot time, a kernel boot option to it. I mean having something like kernel vmlinuz root=/dev/ram0 initrd=linuxrc mymodule.param1="myparamvalue" initrd .... is it possible? Thanks, Luca

Where is 2.6.32?
by Konstantin Svist 07 Mar '10

07 Mar '10

How come Fedora is still on 2.6.31? Is .32 held back on purpose or are there issues merging it? It took less than a week for .31.9 to be pushed through... but I don't see .32 in updates-testing and it's been almost a whole month...

Between F11 and F12, which would you choose?
by Reg Clemens 07 Mar '10

07 Mar '10

I have a half dozen machines updated to F11, and one to F12. Im wondering if I should update the F11s to F12 or leave well enough alone. I realize that the F11 distribution has reached a 'stable' status, and the F12 distribution will probably take a couple more months to reach that status, but would be interested in hearing what other users have to say about the pair. -- Reg.Clemens reg(a)dwf.com

SMS server/gateway
by Jamie Bohr 06 Mar '10

06 Mar '10

I am looking for a SMS server software for RHEL. The phones we use can receive email but it does not always get to the phone in a timely manner and sometimes I get "connected refused" when trying to send messages via email. I've looked at smstools and Googled around but would like the forums opinion on what they have used and experiences. Thank you for your time, -- Jamie Bohr

I'll try these suggestions later today. Note that I was able to disable interrupt throttling on the on-board 82574L NICs without seeing any rx_missed_errors. > > Can you post the output of $ mpstat -P 1 ALL during peak load? > We run "mpstat -P 5 ALL" continuously; is this sufficient resolution? I've attached the mpstat output from the 09:30-10:30 yesterday, which is one of the busiest hours of the day for multicast traffic. Also, here is the top of the output from powertop. Are you running with C-STATE enabled? It is somewhat troubling that more than half of the time is spent in the most power-saving state (C3), but I think this is averaged across all CPUs.

Local cache / 'repo' of updates and added RPM's
by JayLinux 28 Feb '10

28 Feb '10

I had to re-install Fedora 10 on a home desktop PC. In regard to this: Is it possible to have a local cache/ "repository" of all 1) Updates (Critical, Security, Bug-fixes), and 2) Additional installed rpm's (that were installed through PackageKit), e.g. Opera, Adobe Reader, etc. so that I do not have to download all those again (800 MB + D/L) This would be similar to the 'aptonCD' package in Ubuntu ( http://aptoncd.sourceforge.net/) APTonCD is a tool with a graphical interface which allows you to create one > or more CDs or DVDs (you choose the type of media) with all of the packages > you've downloaded via APT-GET or APTITUDE, creating a removable repository > that you can use on other computers. > APTonCD will also allow you to automatically create media with all of your > .deb packages located in one specific repository, so that you can install > them into your computers without the need for an internet connection. Thanks, Jay -- Fedora 10, Ubuntu 9.04 (i686)
