 Posted: Wed Mar 14, 2007 5:49 pm Post subject: JPG image viewer problem [SOLVED] |
 |
|
Hello all,
When I first got into my GNOME environment, I realized that any .jpg file would show up as a generic thumbnail and wouldn't open with Eye of GNOME. So, I thought maybe that was a problem with the image viewer, and I consequently downloaded gThumb. However, I get the same problem with gThumb. Any PNG that I have will show up with all the details in the bottom corner, and it will give me the resized version when I click on "image." JPGs however, say the right file size, but say 0 x 0 pixels and won't show the image.
Here's a screenshot showing the oddity to which I'm referring:

Any ideas what could be causing this problem?
Thanks,
Zach

Do you have the jpeg USE flag on?

EDIT: D'oh... madisonicus was faster 
Anyway - you can check with
| Code: | | emerge --info | grep USE |

DOH! Is there just a gigantic listing of all the USE flags somewhere so I can get it right? Every time I install, I forget a USE flag that I need!
| Code: |
USE="X amd64 berkdb bitmap-fonts cdr cli cracklib crypt cups dri dvd fortran gdbm gnome gpm gtk iconv ipv6 isdnlog libg++ midi ncurses nls nptl nptlonly pam pcre perl ppds pppd python readline reflection session spl ssl tcpd truetype-fonts type1-fonts unicode xorg zlib" ALSA_CARDS="ali5451 als4000 atiixp atiixp-modem bt87x ca0106 cmipci emu10k1x ens1370 ens1371 es1938 es1968 fm801 hda-intel intel8x0 intel8x0m maestro3 trident usb-audio via82xx via82xx-modem ymfpci" ALSA_PCM_PLUGINS="adpcm alaw asym copy dmix dshare dsnoop empty extplug file hooks iec958 ioplug ladspa lfloat linear meter mulaw multi null plug rate route share shm softvol" ELIBC="glibc" INPUT_DEVICES="keyboard mouse" KERNEL="linux" LCD_DEVICES="bayrad cfontz cfontz633 glk hd44780 lb216 lcdm001 mtxorb ncurses text" USERLAND="GNU" VIDEO_CARDS="nvidia nv"

the gigantic listing of all use flags can be found in
/usr/portage/profiles/use.desc and
/usr/portage/profiles/use.local.desc
or you might simply take a look at app-portage/ufed

How would I add the USE flag for jpeg support if I've already installed X and GNOME? Is there a simple way to do it, or will I have to actually recompile it all?

you have to recompile, but luckily emerge has an option to find the packages that use the new useflags:
| Code: | --newuse (-N)
Tells emerge to include installed packages where USE flags have changed since compilation. |

Excellent. I'm surprised that jpeg isn't a default USE flag because of common it is. Anyway, thanks for the help!

Pretty sure that it is a default flag if you're using a desktop profile.

Oh, I'm just using the default profile; not the desktop one.
