Plotting in R
Hello!
I'm an Ubuntu newbie, and I'm trying to get R working properly with Edgy. A problem I'm having is that R doesn't seem to make any plots. For instance, if I type
or
the cursor simply blinks, and nothing happens. Also, I can no longer input anything in R, but have to close the terminal window. Is there any way to find out what is going wrong? There are no error messages or anything, and I don't know if it's a problem with R, X11 or Edgy. I've tried completely removing and reinstalling R.
Thanks, and I look forward to trying any ideas!

P.S.: I've previously made some changes to the xorg.conf to get it to work with my ati drivers (installing fglrx and so on -- maybe that could have messed up the settings that R needs?)

Re: Plotting in R
I have a very similar setup with ATI and fglrx on edgy. R works and plots perfectly. Check if /var/log/Xorg.0.log has any clues.
Code:
grep '(EE)' /var/log/Xorg.0.log

Re: Plotting in R
Thanks for your reply, amd-64!
The command you suggested gives the following output:
Code:
(EE) AIGLX error: dlsym for __driCreateNewScreen_20050727 failed (/usr/lib/dri/fglrx_dri.so: undefined symbol: __driCreateNewScreen_20050727)
(EE) AIGLX: reverting to software rendering
(EE) xf86OpenSerial: Cannot open device /dev/wacom
(EE) xf86OpenSerial: Cannot open device /dev/wacom
(EE) xf86OpenSerial: Cannot open device /dev/wacom
(EE) xf86OpenSerial: Cannot open device /dev/wacom
(EE) xf86OpenSerial: Cannot open device /dev/wacom
(EE) xf86OpenSerial: Cannot open device /dev/wacom
I don't think it's a problem with a wacom (or lack thereof), but I don't know what the AIGLX error refers to ... could that be the problem?
I can post my xorg.conf if you think that will help find the problem. Thank you again for helping.

Re: Plotting in R
please post your xorg.conf. Are you using compiz or beyrl. You may want to test using the ati or radeon drivers instead of fglrx. This involves replacing the fglrx entry under device in xorg.conf with radeon or with ati.
Alternatively, you could backup xorg.conf and create a new one with
Code:
sudo dpkg-reconfigure xserver-xorg

Re: Plotting in R
Hi amd-64, sorry about the delayed reply, I was away for a while. Here's my xorg.conf:
Code:

#
# This file was generated by dexconf, the Debian X Configuration tool, using
# values from the debconf database.

# (Type "man /etc/X11/xorg.conf" at the shell prompt.)
#
# This file is automatically updated on xserver-xorg package upgrades *only*
# if it has not been modified since the last upgrade of the xserver-xorg

I tried using sudo dpkg-reconfigure xserver-xorg, but the resulting xorg.conf didn't work at all (my screen just said "Cannot use this display mode", or something like that)
I don't know what compiz or beryl are, so I don't know which one I am using. Thank you for helping!

Re: Plotting in R
While I do not know if it makes any difference, you should remove this section from xorg.conf
Code:
Section "Device"
Identifier "ATI Technologies, Inc. RV370 5B60 [Radeon X300 (PCIE)]"
Driver "ati"
BusID "PCI:1:0:0"
EndSection
You can also try going back to the open-source ati driver by replacing "fglrx" with "ati" or "radeon".
You should check is if you have all the packages needed to plot in R. It is not clear to me what packages provide the plotting. As a minimum, r-base and r-recommended are a good starting point.
If all else fails, you should also check if a log is made in any of the files in /var/log when you issue a plotting command
will sort the files with the most recent at the bottom.

Re: Plotting in R
Thanks for your help! Turns out that there were several problems with the xorg.conf -- Not only were there two devices (as you noted), but there were also two monitors and two screens specified. Merging the sections and keeping the relevant settings made it work. Also, there were problems with the HorizSync and VertRefresh settings for the monitors.
Here's the working xorg.conf:
Code:
# /etc/X11/xorg.conf (xorg X Window System server configuration file)
#
# This file was generated by dexconf, the Debian X Configuration tool, using
# values from the debconf database.
#
# Edit this file with caution, and see the /etc/X11/xorg.conf manual page.
# (Type "man /etc/X11/xorg.conf" at the shell prompt.)
#

# if it has not been modified since the last upgrade of the xserver-xorg
# package.

# again, run the following command:
