Topic: [Solved] Emacs as Root | [Solved] Slow Emacs Scrolling

Running 'sudo emacs -nw ....' works, but does not give me any of the customizations in my ~/.emacs file. This is because emacs is looking in /home/root/.emacs? I created a soft link from my ~/.emacs to the root's home, but then emacs was not happy about other code it required in ~/.emacs.d/. I'm sure I didn't need to do all this on Ubuntu (I'm not "complaining" about #! and being an Ubuntu fan-boy, I'm just making the comparison) -- so there must be a way around this?

It's located in /root/.emacs, so copy the contents from all the config files and folders there.

Re: [Solved] Emacs as Root | [Solved] Slow Emacs Scrolling

Do not run emacs as root - there is no need to.
You can access any file on any mounted partition from within your user started emacs!
Suppose you want to edit /etc/network/interfaces - owned by root, not allowed to be edited by any normal user:

Ctr+x+f
/sudo::/etc/network/interfaces
You will have to enter your password if you have sudo set up that way.

Emacs - started as your user - will open a buffer, and allow you to edit/write back the buffer

If the file is not even write-able by root, e.g. /boot/grub/grub.cfg

/sudo::/boot/grub
search for grub.cfg: Ctrl+s grub[tab]
enter ! enter
chmod +w enter
the file is loaded and editable
edit it
save
Xtrl + x K
to kill the buffer
! enter
chmod -w
restores the no-write permission for the file

You want to edit a file on /dev/sdd? /dev/sdd is not mounted yet? ( I suppose you have pmount installed - if you have not, install it first )

From within emacs:
Alt + x
pmount /dev/sdd
Ctrl +d
to close the shell
Ctrl + x + f
/sudo::/media/sdd/.....

Emacs is an OS - No need to leave emacs to do anything else - well, almost smile

Edit: I have emacs open full screen in one workspace, iceweasel in another workspace and 3 instances of terminator in a third workspace. I can do everything I want with that setup.

Re: [Solved] Emacs as Root | [Solved] Slow Emacs Scrolling

@xaos52: Thanks. I tried your suggestions, but could not get them to work until I realized I have an old tramp-default-proxies-alist setting in my .emac which I need to sort out first.

Re: [Solved] Emacs as Root | [Solved] Slow Emacs Scrolling

^ I commented out the tramp-proxies thing and restarted emacs and entered the filename as you suggest and it worked. After typing the "e" of "etc" I am prompted for my password and I can then enter the filename I want to edit as root. Thanks.

I see a "@" appears in the mode-line to indicate that I am editing a file on a "remote" machine.

Re: [Solved] Emacs as Root | [Solved] Slow Emacs Scrolling

^xaos52: Just out of interest -- the emacs you have open and running all the time -- GUI or console version?

Re: [Solved] Emacs as Root | [Solved] Slow Emacs Scrolling

GUI
Of course I occasionally use emacs at console for repairing things, but there also, I run it as my user, and use the /sudo:: syntax to access files with root permission. I do not keep that instance running all the time.
Cheers.

Re: [Solved] Emacs as Root | [Solved] Slow Emacs Scrolling

^ I typically use emacs -nw for the console version, although I am familiar with the GUI version. I opened a small (8.5kb) file today in the GUI version. It opened as a non-full-screen window and scrolling through the file was fast and responsive. I maximized the emacs window (1920x1080) and noticed that scrolling was very slow and laggy -- the selection line would jump a few lines at a time. The lines in the text file were fairly short and there was not a large amount of text. I'm using a quad-core machine with 2GB of RAM running #! r20111125 32-bit with an nVidia card and proprietary drivers. Any ideas on why performance in emacs would be so poor?

That is not normal. Emacs should fly with those specs.
What video driver are you using?

I have 1280x1024 resolution, but I am using the VESA driver, because KMS does not work for my Nvidia card. I could, and sometimes do install the Nvidia proprietary driver, but usually I do not even bother.

My response times in Emacs are excellent.
I do not have any special scrolling commands in my .emacs - I checked.

Re: [Solved] Emacs as Root | [Solved] Slow Emacs Scrolling

@xaos52: Thanks. I'm "stuck" in a way because the nouveau drivers (for nVidia) don't always work properly (I've been told/read) and can cause the cards to overheat, but provide proper frame-buffer support and good performance in Firefox/Iceweasel.

The proprietary drivers don't offer proper frame-buffer support and result in very sluggish performance in Firefox/Iceweasel, but don't cause the cards to overheat. Maybe I need to add "Emacs" to the list of programs which have sluggish performance now.

I have on-board Intel graphics IIRC, but have a 22" and 23" monitors connected via DVI to the nVidia, so I can't really switch to using the on-boards graphics without returning to only one monintor.

Re: [Solved] Emacs as Root | [Solved] Slow Emacs Scrolling

Have you tried the nouveau driver? Perhaps there are still some things that need to be ironed out, but it has improved a lot. I am sure it would solve your Emacs problem.

When it runs too hot, try to find a solution using the pm-tools.

A shame really, not using the full power of that Nvidia card.

Cheers!

Edit: I misread your post. You are using the nvidia driver. What version are you running? Dit you install it using apt-get or did you download the blob from the nvidia site?

Mind posting your 

/var/log/Xorg.0.log

Re: [Solved] Emacs as Root | [Solved] Slow Emacs Scrolling

@xoas52: Returning to the open drivers for my NVidia card not only solved the terribly sluggish performance in IW 9 and 10, but also seems to have solved the Emacs GUI full-screen scrolling issue. I can't recall which file I was scrolling before, but it was 8.5kb according to my post. I've just tested with the Xorg log of ~55kb, and it scrolls fine in the GUI version at 1920x1080 resolution with a selection bar/line. Maybe it was related.
