Re: [CentOS] NetworkManager trouble with CentOS 5.4 and KDE3
Martin Jungowski wrote: I'm evaluating CentOS 5.4 for our company and one of our requirements is that it must also run on laptops. I've managed to get everything working so far except for wireless networks. The problem here seems to be that CentOS fails to provide a knetworkmanager package, and we're using KDE3 for various reasons. Thus, we're limited to Networkmanager-gnome which works but fails to save passwords in KDE3 and only works in Gnome. Of course kwallet is installed but requires knetworkmanager to work. The only solution I found so far was to log into Gnome, connect to the wireless network and save the password but that's certainly NOT an opion. I guess the question is quite simple: how do I get NetworkManager to save passwords in KDE3? It's a critical issue and switching to Gnome is not an option either. Infact it's Novell's decision to ditch KDE3 and focus on KDE4 instead that made us turn our backs on openSUSE in the first place. So, is it possible to solve this teeny-tiny problem some other way? There was a thread, NetworkManager won't save wireless keys, on this list on January 14, 2010. I don't know if it was your problem exactly.

[CentOS] 32bit development on x86-64
We develop software and are beginning a slow transition from 32 bit
applications
to their 64 bit equivalents. During this period it will be necessary to
build
programs targeted for both environments using the x86-64 machines for
development.
here is a simple/small application, sizes.c:
#include stdio.h
#include stdlib.h
int main(int argc, char **argv)
{
printf(Various sizes:\n);
printf(short= %d\n, sizeof(short));
printf(int = %d\n, sizeof(int));
printf(long = %d\n, sizeof(long));
printf(float= %d\n, sizeof(float));
printf(double = %d\n, sizeof(double));
return 0;
}
if I build it using:
gcc -m32 -Wall -osizes sizes.c
there are no warnings or complaints and a functioning 32 bit
program runs, giving the size of a long as 4 bytes. (Of course
without the m32 flag the size of long is 8 bytes.)
if I try to do the equivalent in two steps:
gcc -c -m32 -Wall sizes.c
gcc -osizes -Wl,-m,elf_i386 sizes.o
the result is:
/usr/bin/ld: skipping incompatible
/usr/lib/gcc/x86_64-redhat-linux/4.1.2/libgcc.a when searching for -lgcc
/usr/bin/ld: skipping incompatible
/usr/lib/gcc/x86_64-redhat-linux/4.1.2/libgcc.a when searching for -lgcc
/usr/bin/ld: cannot find -lgcc
collect2: ld returned 1 exit status
there is some confusion in the man pages as to whether the correct 32
bit emulation is elf_i386 or i386linux so:
gcc -osizes -Wl,-m,i386linux sizes.o
gives result:
/usr/bin/ld: unrecognized option '--eh-frame-hdr'
/usr/bin/ld: use the --help option for usage information
collect2: ld returned 1 exit status
since the single line command works it seems that there must be a way to
get the job done.
This becomes important when there are many source files and use of a
traditional
makefile is involved where compiling and linking are separate steps.

My Printer/Scanner is HPc6180. Do you have HPLIP installed? The version that comes with CentOS is so old that (1.67, I think) that if you have a printer newer than about four years old it won't be supported. I seem to be able to fake the printing part by selecting another printer that should be similar. The scanning part however is not so simple it seems. I installed HPLIP version 3.9.8 and after a grueling effort to satisfy the dependencies, except for dbus-python or python-dbus, it seems to be referred to both ways. HPLIP still claims that it is not installed even though it is. Perhaps my version, although up to date according to yum, is too old. In any case my printer is supported and I was able to scan one frame and then it never worked again. On any attempt to scan xsane puts up a dialog that says Failed to open device 'v4l:/dev/video': Invalid argument and then quits. That device I think is the camera which was there and working fine when the single scan succeeded. My Windows XP computer is able to scan so I am confident that the printer hardware is not at fault.

Re: [CentOS] bluetooth mystery
Preston Connors wrote: -BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Roger K. Wells, On my older Think Pad I had a similar problem with devices, such as WLAN and Bluetooth, shutting off and not showing up in Linux for no apparent reason. Every so often I would have to ensure that the BIOS settings had the device enabled, that other Operating Systems on the computer didn't have the device disabled, and that I didn't accidentally hit the physical switch on the computer disabling the device. I found that most times the other operating system (Windows XP at the time) had the device disabled for an unknown reason and that re-enabling the device in the other operating system allowed the device to properly operate in Linux. Thanks for the response. I feel really dumb. The physical switch had been turned off. I have had several ThinkPads and this is the first with an actual switch, on all the others the power to the radios was controlled via software. thanks again, roger Roger K.

[CentOS] Microsoft Mouse 5000 - Bluetooth
Has anyone been able to get the scroll wheel to work? Most of the other functions are fine, however xev does not show any events when the scroll wheel or the fourth button is pushed. Other than that it is a nice mouse but I would like the scroll wheel to work.

Here is the relevant bug tracker: http://bugs.centos.org/view.php?id=3544 The current cplus kernel has the following: CONFIG_MAC80211_LEDS=y CONFIG_IWLWIFI_LEDS=y CONFIG_IWLAGN_LEDS=y CONFIG_IWL3945_LEDS=y # CONFIG_RT2400PCI_LEDS is not set # CONFIG_RT2500PCI_LEDS is not set # CONFIG_RT61PCI_LEDS is not set # CONFIG_RT2500USB_LEDS is not set # CONFIG_RT73USB_LEDS is not set Please be sure to read http://wiki.centos.org/AdditionalResources/Repositories/CentOSPlus before using the centosplus repository. Thanks for your reply. I did the iwl5000-firmware installation that Ned Slider advised and the radio appeared to start working. I then did the transition to the centosplus kernel, following the directions in the link that you provided, and then the LED started working.
