fedora 20: dell broadcom wifi not running after update to kernel-3.17.8

so, i was trying to make my bluetooth run, when i upgraded my kernel to 3.17.8 and lost my wifi

 i did my usual kmod-wl install (http://linusramos.blogspot.com/2014/01/fedora-20-dell-install-broadcom-wifi.html) but it didn't work

got - Requires: kernel-uname-r = 3.17.7-200.fc20.x86_64

 so i installed akmod-wl via yum instead

 that's it!

fedora 20: shutdown freezes

yep, after solving my start-up issue, i got a shutdown issue. shutdown button and terminal commands from my gnome freeze my box. only a force shutdown via the power button works. when i started searching the internet for solution, i found a great amount of bug reports and call for help, earliest on fedora 16, which has no response for solution. i read somewhere that it could be a kernel issue, though, i doubt it because it has been experienced even in old fedoras. what solved my issue? a kernel update via yum.

# yum update kernel

somehow it fixed something. so i'll stop playing around with my box, for now. i can wait till there's a new kernel i can update to, in case i face another shutdown issue.

fedora 20: start-up hangs after trying to install nvidia video card

i remember trying to install my nvidia geforce 625m video card on my dell 3421 early this year, and failing. yesterday, i tried running the installer again (and other nvidia drivers) but resulted to my fedora hanging after "manage, install and generate color profiles".

solution was to totally remove all nvidia installations on my box.
you can go ctrl + f2 for a command shell, then

# yum remove *nvidia*

and then reboot.

fedora 20: linksys ae3000 usb wifi

i have a dual boot win 7 and fedora 20 desktop that uses a linksys ae3000 usb wifi. usb wifi plug-and-plays on win 7 but doesn't on fedora 20.

so, i found this easy installation howto buy a guy named Balaji Ravindran:

his steps include just the ff:

1. download and extract source driver
2. install prerequisites
3. edit device file
4. compile and install driver
5. run depmod and modprobe
6. +1 for him! ;D

fedora 20: sd card reader set up (with warning)

i finally needed to use the sd card reader of my dell laptop and found out that it was not set up to run.

i found a website with the title Running Fedora Linux on Dell Laptops (http://www.arachnoid.com/linux/dell_laptops_on_fedora.html) and found a solution there to make the sd port work with just two steps:

1. create a file /etc/modprobe.d/cardreader-firewire.conf with the value:

options firewire-ohci quirks=0x10

2. recreate initramfs image

# dracut --force

after reboot, your sd card reader should work.

warning, though. my wifi stopped working after my reboot. i had to update my wifi and reboot again:

# yum update kmod-wl
# reboot


if no kmod-wl update is available, you can try uninstalling and reinstalling kmod-wl and see if that works.

fedora 20: dell broadcom wifi not running after update

after having my broadcom wifi work on my dell running fedora  20 (http://linusramos.blogspot.com/2014/01/fedora-20-dell-install-broadcom-wifi.html) i updated by fedora. then my wifi couldn't detect anything anymore. tried reinstalling drivers a couple of times and even installing other things. restarted by pc too many times. then i read somewhere that secure boot hinders one of the procedures in installing one of the drivers available. so before trying to reinstall, again, i turned off secure boot. yep, my wifi worked again even without installing the other driver i found.

what's with secure boot stopping my dell-broadcom-wifi-on-fedora-20 from WIFIing?? :P

fedora: check temperature

felt my pc's fan blowing off hot air (as it should) and got curious how high the temp was. so, i looked for a way to check:

1. install
# yum install lm_sensors.x86_64

2.1. check
# sensors

2.2. or watch
# watch sensors

 

 ...i'm not that good a judge of hotness after all ;))

fedora 20: install viber

i'm sure you've heard of viber. it's available on desktops too. even on linux desktops! here's how i got it installed on my 64bit fedora 20:

1. download and extract http://download.cdn.viber.com/cdn/desktop/Linux/Viber.zip
    i extracted the Viber folder in my /home/user/ directory

2. change the ownership of your viber directory to your user; to do it on the terminal:
    # cd /home/user/
    # sudo chown -Rf user:user Viber

3. make Viber and Viber.sh executable by changing their permission; to do it on the terminal:

    # chmod +x /home/user/Viber/Viber
    # chmod +x /home/user/Viber/Viber.sh

4. test by running Viber.sh shell script:

    # /bin/sh /home/user/Viber/Viber.sh

viber on!
