 |
|
Wow it took a long time to emerge and compile all of that. I didn't go for the binary.
But it seems to work pretty great! Provided I run it as root, that is. If I try executing
as a normal user, I get
| Code: | normaluser@localhost ~ $ firefox
Segmentation fault |
I saw a thread of people recommending to unmerge gconf and delete the directories and then re-emerging gconf, but I actually didn't even have gconf to begin with. So I emerged it, and it didn't change anything.

1) Which version of Firefox did you install?
2) Please post the output of 'emerge --info'
3) Does Firefox also crash if you start it with a new (empty) profile?
| Code: | cd ~
mv .mozilla .mozilla.backup
ls -la .mozilla .mozilla.backup # Make sure the 'mv' worked
firefox # What happens?
rm -rf .mozilla
mv .mozilla.backup .mozilla |

Hello. I installed firefox 60.4.0esr (64-bit)
Changing profile/using empty one did not change anything. (Same behavior occured as in OP)

I don't see anything totally wrong in the output of 'emerge --info'.
Are there any messages in the log files (/var/log/... or journalctl -e) after the segfault?
Could it be related to the use flags below?
| Code: | | system-harfbuzz system-icu system-jpeg system-libevent system-libvpx system-sqlite |
I don't use those use flags for two reasons:
- There's probably a reason why Mozilla ships Firefox with their own version of the libraries
- Using system libraries may cause frequent rebuilds of Firefox - something I don't want

Please collect and post a backtrace of the crash.
Using system libraries is generally correct. Switching to the bundled versions is only advisable if you suspect that upstream has broken their support for system libraries. We don't have any indication of that yet. |

| Hello, thank you Hu. I'm not sure what you mean by "Please collect and post a backtrace of the crash." I'm very new to Gentoo. Firefox isn't crashing, because I can't get it to start. If I execute firefox as a non root user, it doesn't start, it only returns in the terminal "Segmentation fault." This is the first time I've ever installed FF on Gentoo. It's running perfectly as a root user, though. No issues at all. |

What you should avoid.
Please could you emerge "strace" and run - as non-root user - | Code: | | strace -o strace.log firefox |
and post here the relevant part (or the link got from wgetpaste)? |

Also I ran this code because someone said it would keep me up to date:
| Code: | | emerge -uUD --ask --newuse --keep-going --with-bdeps=y @world |
(I really don't know for sure what that command did) but it rebuilt everything it seems, including FF. No changed behavior after. Although that took a really damn long time. And then FF rebuilt. Lol

When you do plain su (not su -) you will be root in users home directory. Some applications write back their conf files every time they terminate, meaning you may create conf files owned by root in your home. You could run chown recursively on your home directory to make sure there are no files owned by root and never use plain su again.
If you create a new test user, will Firefox run?

What settings do you recommend I create the new user with? Because the new user that isn't working was made with the wiki
| Code: | | useradd -m -G users,wheel,audio -s /bin/bash larry |
default suggestions. I'm starting to wonder if these permissions aren't correct. For example, I'm not in the video group. Yet I am able to run startx.
edit: I made a new user with a few more groups. It works. By the way, when you say never use su again I assume you mean just for Firefox never use it again.. I'm glad the new user works. |

| He said never use plain su again, and meant exactly that. Implicitly, you should instead run /bin/su -, so that you get a clean environment for your root shell. |

Interesting, I've never really read much about su/ vs su -.
Have I created a mess in my system by using su and/or su -interchangably? I'm sure I've ran a lot of commands with both. I didn't even know until now that they weren't just the same command.
Why does Gentoo still support su if it shouldn't be used? See, this is why I wanted to switch to Gentoo since forever, now. I felt like the nuance was optional. Here you have to know it. |

There are cases when su can be used, say, I want to test some application and I build it as user. Then I do su in build directory and execute 'make install'. But I could do same with 'su -', I just need to navigate into build directory beforehand in this case, so plain su will save me a few keystrokes. You chose to ignore may advice about running chown recursively on your home directory?

I had some difficulty placing the context of your chown recommendation. I don't know this command. I ran chown -R in my home directory and I got "Missing operand." The --help isn't helping me very much.
I still have some "permission denied" reports for various directories when I use Firefox in the new account (if I Control+F1 inside X) but other than that Firefox works as the new user.
stuff like "dconf-WARNING unable to open /usr/local/share/dconf/profile/user (pemission denied)."
I didn't really ignore your advice, I just had not enough experience to contextualize the unfamiliar command. I'm just really wishing I had ventured into this [Gentoo] a long time ago. Because clearly most of my Linux years have been wasted on superficial knowledge, most of which is acquired in the first 10 minutes of installing Gentoo. While I don't feel wildly lost in all of this, it's just clear how much time I wasted. I'd be a lot less lost if I had actually learned how linux works, to start with. But wow, to even call myself a linux user before almost seems like an insult, now.
re SU: I won't run su ever again, I'm just still really curious about what discrepencies I have introduced now by using that (and wondering if I should just reinstall my whole system, now, because I've definitely been using those commands interchangably on all my installations for like 10 years now) |

Although not about Firefox, I don't think I've ever run "su -". I've been using just su almost daily for a 15 years for system maintenance and updates on over a dozen machines without issue. I should change?

--> (Don't ask me, LOL)
If it's literally just about changing directories, then yes, of course I've noticed that su leaves me at the directory I log in as an su - changes me to root's ~homdir. Other than that I am not aware of a difference |

Gen3Hunna, the command would be:
| Code: | | chown -R username:groupname /home/username |
This will ensure that you and your chosen group own all of the files in your home directory.
FYI, my firefox is built with the following:
| Code: | | [ebuild R ] www-client/firefox-60.4.0::gentoo USE="dbus gmp-autoupdate screenshot startup-notification -bindist -clang -custom-cflags -custom-optimization -debug -eme-free -geckodriver -hardened -hwaccel -jack (-neon) -pulseaudio (-selinux) -system-harfbuzz -system-icu -system-jpeg -system-libevent -system-libvpx -system-sqlite -test -wifi" L10N="-ach -af -an -ar -as -ast -az -bg -bn-BD -bn-IN -br -bs -ca -cak -cs -cy -da -de -dsb -el -en-GB -en-ZA -eo -es-AR -es-CL -es-ES -es-MX -et -eu -fa -ff -fi -fr -fy -ga -gd -gl -gn -gu -he -hi -hr -hsb -hu -hy -id -is -it -ja -ka -kab -kk -km -kn -ko -lij -lt -lv -mai -mk -ml -mr -ms -nb -nl -nn -or -pa -pl -pt-BR -pt-PT -rm -ro -ru -si -sk -sl -son -sq -sr -sv -ta -te -th -tr -uk -uz -vi -xh -zh-CN -zh-TW" 0 KiB |
I only switched from firefox-bin to firefox recently to avoid pulseaudio.

Probably not, system maintenance is not running user applications, in other words, you use elevated rights sensibly. I'd still recommend to use 'su -' instead of 'su'.

I recall having a problem once and on the forum was told that there is an environment difference too. Mostly it doesn't matter. I don't normally use "su -" unless I'm actually going to work in the root directory, but at least once, I had different behavior between "su -" and "su".
EDIT:
Like if I want to mount or unmount something, I'll just su, do my work and exit back to the user shell. I get tired of always having to "sudo lspci" and such. |

About su and su -, here is what the su manpage says [Note: "-" is the short form of "--login root"]:
| Code: | The $HOME, $SHELL, $USER, $LOGNAME, $PATH, and $IFS environment variables are reset.
If --login is _not used_, the environment is copied, except for the variables above.
If --login is used, the $TERM, $COLORTERM, $DISPLAY, and $XAUTHORITY environment variables are copied if they were set.
If --login is used, the $TZ, $HZ, and $MAIL environment variables are set according to the /etc/login.defs options ENV_TZ, ENV_HZ, MAIL_DIR, and MAIL_FILE (see below).
If --login is used, other environment variables might be set by the ENVIRON_FILE file (see below).
|
Also,
| Code: | | The - option may be used to provide an environment similar to what the user would expect had the user logged in directly. |
When not used,
| Code: | | The current environment is passed to the new shell. The value of $PATH is reset to /bin:/usr/bin for normal users, or /sbin:/bin:/usr/sbin:/usr/bin for the superuser. |
So, if you *truly* want to act like the user you are switching to, you use "-". With su, you just get a bland PATH.
I didn't even know there was a difference! Thanks, Jaglover! |
