times new roman courier helvetica fonts in matlab linux ubuntu plots

In general matlab plot fonts are not clearly visible in linux especially in ubuntu.

There we need to install some fonts.

open terminal by pressing Alt+Ctrl+T

then enter the following:

sudo apt-get update

sudo apt-get install gsfonts-x11

This will install only Helvetica very small and very large fonts.

to install intermediate size fonts also

enter the following command in terminal:

sudo apt-get install xfonts-75dpi xfonts-100dpi

But still times new roman and courier arial etc truetype fonts will not work yet...

installation of ttf-mscorefonts-installer also will not serve the purpose.

ie;  sudo apt-get install ttf-mscorefonts-installer

The problem is that in linux matlab we need postscript fonts to display in figures

ie; the font files with an extension .pfb, .afm etc...

Here is a list of fonts available online.

/AlbertusMedium               (0001____.pfb) ;
/AlbertusExtraBold            (0002____.pfb) ;
/AntiqueOlive                 (0003____.pfb) ;

/Garamond-BoldItalic          (0015____.pfb) ;
/LetterGothic                 (0016____.pfb) ;
/LetterGothic-Italic          (0017____.pfb) ;

/Univers-Italic               (0030____.pfb) ;
/Univers-Bold                 (0031____.pfb) ;
/Univers-BoldItalic           (0032____.pfb) ;
/UniversCondensed             (0033____.pfb) ;
/UniversCondensed-Italic      (0034____.pfb) ;
/UniversCondensed-Bold        (0035____.pfb) ;
/UniversCondensed-BoldItalic  (0036____.pfb) ;
/Arial-Roman                  (0037____.pfb) ;
/Arial-Italic                 (0038____.pfb) ;
/Arial-Bold                   (0039____.pfb) ;
/Arial-BoldItalic             (0040____.pfb) ;
/TimesNewRoman                (0041____.pfb) ;
/TimesNewRoman-Italic         (0042____.pfb) ;
/TimesNewRoman-Bold           (0043____.pfb) ;
/TimesNewRoman-BoldItalic     (0044____.pfb) ;
/Symbol                       (symbol__.pfb) ;
/Tidbits                      (tidbits_.pfb) ;

The download link is here:

Download the file and keep it on Desktop.

Then open a terminal by "Alt+Ctrl+T"

and enter the following commands:

cd Desktop

tar -xzvf truetype.tar.gz

sudo cp -r truetype /usr/share/fonts/X11/

sudo fc-cache -fv

This will make the truetype fonts clearly visible in matlab linux...

But this is also not a complete solution...

Some very large and some italic fonts are not working properly...

But it is a major step forward for the basic problem...

Bootmgr is missing after Grub Restore

If you windows is reinstalled after Linux, and then grub is restored in the recent versions of grub one may come across the problem in windows booting:

 BOOTMGR is missing 
Press Ctrl+Alt+Del to restart

This is because, grub-restore will just recovers the earlier configuration file which contains the information about the UUID (Universally Unique IDentifier) of the earlier partition.

A simplest solution for this is to comment the line with -fs-uuid for windows partition.

To do this open terminal from Applications --> Accessories --> Terminal
Then type in:

gksudo gedit /boot/grub/grub.cfg

Find out the menu entry for windows ie;

the entry which starts with
#menuentry "Windows xxxxxxxx (loader) (on /dev/sdax)"{

With in that entry put a # symbol before the line

#        search --no-floppy --fs-uuid --set xxxxxxxxxxxxxxxxx

Then save the file, close and restart the system to go into windows...

Installing g77 in Ubuntu intrepid (8.10), Jaunty (9.04), Karmic (9.10), Lucid (10.04), Maverick (10.10), Natty (11.04)

g77 is a part of gcc (GNU Compiler Collection) provided by GNU. But GNU stopped supporting it from gcc-4.2. Current Ubuntu versions starting from Ubuntu 8.10 (Intrepid) are using gcc-4.2 or higher. Current Ubuntu Maverick is using gcc-4.5. So to install g77 we need to install gcc-3.4. This package is included in the "universe" repositories of Ubuntu "hardy" distribution. Hence to install g77 in Ubuntu Intrepid, Jaunty, Karmic, Lucid, Maverick versions we need to add the hardy universe repository to the sources.list. Here is the procedure for it.
