How to return to the Desktop Environment from tty in Fedora

I.had.to.Google.like.MAD  photo piangry.gif to find this solution  photo emo.gif

All you have to do is press:

Ctrl+Alt+F1

You enter tty from the Desktop Envrionment by pressing  Ctrl+Alt+F2 up till Ctrl+Alt+F6 .

If  you want to switch between several tty’s, like  if you are for example in tty3 and want to go to tty2 all you have to do is hit Alt+F2 and you are in tty2. Nice huh?

Btw, let’s not use the comment section of this post to debate my Google skills okay  photo talktothehand.gif

Regarding the “Invalid partition table!” error in Fedora on a Dell E5250

invalid_partition_table

If you get this during the boot process of Fedora, you might know that pressing on enter will continue the boot process. If you however don’t want your boot process to stop at the “Invalid partition table!” error, then you should do the following. With the next installation of Fedora, choose “standard partition” in the Anaconda installer (see picture below), the default setting is “lvm” which is the cause of this error.

standard_partition

 Edit: I know on the Dell site, people blame this error on an outdated BIOS. But I still got this error after updating my BIOS.

How to install Skype on Fedora 64 bit

Just to be clear upfront this won’t work in Fedora 32 bit. If you have no clue what version you are running  photo shadey.gif check this by typing this command in your terminal:

uname -mrs

This is what I see when I type it:

cliccie for larger piccie

cliccie for larger piccie

The 64 in my case indicates that I am running 64-bit. If I were running 32-bit, both numbers would have been 32  photo puh2.gif

Okay, let’s get stared  photo nodding.gif  log in as root in terminal. You do this by typing:

How to check how your BIOS and RAM in Fedora without a reboot

So while I was going through one of  Professor Messor his CompTIA A+ training videos, the computer I was working on started to make a beeping sound and I saw an orange light flashing. If it weren’t stressing me out right now, (I’m broke) it would be funny  photo emo.gif I mean what better way is there to test what I’ve learned so far, huh?

Well a quick Google search taught me that each BIOS manufacturer has his own list of beep codes. So step one is to check who the manufacturer of the BIOS is, I could restart the computer, but I am lazy and impatient  photo talktothehand.gif.

There is a way, of checking who your BIOS manufacturer is without restarting your pc. You can do this by using a command line program called dmidecode .  A command line program(or utility) is a piece of software that can only be opened  in, and/or used through the terminal.

How to install dmidecode

  • open terminal
  • log in as root
  • type “yum install dmidecode” (without the quotation marks)

install dmidecode

At one point during the installation you will be asked to type “Y” or “N”, type “Y”.

So now we have dmidecode installed, let’s check who the BIOS manufacturer is.

  • make sure you are still logged in as root
  • type “dmidecode –type 0”

Et voilà, there is the name of the vendor!
checkbiosvendor

As you can see in my case the vendor is “American Megatrends Inc.”, according to their AMI beep code list, one beep refers to “DRAM refresh failure” which means “The programmable interrupt timer or programmable interrupt controller has probably failed” photo what.gif

So I have a problem with my DRAM……. Hmmm, now what?

Well, I guess I have to check what kind of RAM I have.

  • type in terminal ” dmidecode –type 17″

howmuchram

(Warning, this message shows the info per piece of RAM that’s installed. I have four pieces of RAM installed, and the picture above shows info about the first piece only! (I didn’t want to bore you with a large picture). So don’t forget to scroll down to check the info of all the RAM’s!)

So I have 4 pieces of DDR2,  each with the size of 1024 MB  and a speed of 800 MHz.

So now what?

Edit:

While typing the tutorial, I took a look at the backside of my tower and there are two circles behind it, I think those are vents. Or one of them is I think, I swiped it with my hand only to get an almost “Mano Negra” so much dust  photo redface.gif!

When  continuing with this tutorial the beep eventually stopped and the fan is less noisy photo clown.gif but the orange light is still flashing…. I am pretty sure the thing always flashed, so I think I am going to leave it at this.

And yes, I am not only lazy but also gross. My ex-boyfriend, a total Alpha-male, once said about my keyboard:”Roja, your keyboard is gross, not just gross but really gross”. Ya’ll know, when an Alpha-male tells you something is gross, it really is gross  photo loveit.gif
