 Posted: Wed Jun 29, 2011 4:11 pm Post subject: having problems opening programs |
 |
|
when I try to open programs from command line or the icon this shows up
| Code: |
firefox
No protocol specified
No protocol specified
Error: cannot open display: :0
|
I cannot execute any of my programs and I've seen forums thinking that this is all related to wpa_supplicant changing the hostname on dchcp or something like that here is the forum

but this seems to be a solution for arch so I'm not sure if the same would apply to gentoo |

| Is that problem occurs on a fresh install system or after an upgrade ? |

My apologies Eddi3x3. I had not paid attention to the index.
Maybe it would be interesting if you say what desktop environment you are using, do you use a desktop manger or just startx.
emerge --info would be important too. |

Eddi3x3, is this a new symptom? Were you ever able to open firefox in your newly installed Gentoo?

| yes I've opened firefox but after 3 reboots it stopped working and that forum made me believe that wpa_supplicant might be to blame unless u have an idea what it could be; I'm using kde desktop |

But you can log in to KDE just fine, right? Can you open anything else? For instance, try opening the "System Settings" app. Can you open a terminal?
Besides rebooting, you installed wpa_supplicant, right? Did you get it working? Did you install anything else?

| sometimes when i boot up, everythig works fine but most of the time i cannot launch any applications i have installed; I can open applications no problem BEFORE wpa_supplicant gets a stable conneection to wi fi and the forum talked about how wpa_supplicant changes a host name when it uses dchcp |

Is your network up? Could you open a terminal, change to root (using su), and post the output of the following, please: | Code: | ifconfig
hostname
ping -c3 google.com |

| I have internet access, that is clear, pings work but when WPA_supplicant connects to a network it CHANGES the hostname for some odd reason on my computer so when I try to open a program is shows up as though it doesn't exist on my comp and the above shows up; where can I set a static hostname (if that can happen) |

Can you post the contents of "/etc/conf.d/hostname", please? Also, what version of baselayout do you have installed? You can run | Code: | | equery list -i baselayout |
to find out.
