GunJack's questions

Hi just installed Apache2 on Ubuntu 20.04. Added myself to www-data group. id prateek

uid=1000(prateek) gid=1000(prateek) groups=1000(prateek),4(adm),24(cdrom),27(sudo),30(dip),33(www-data),46(plugdev),120(lpadmin),131(lxd),132(sambashare)

changed the ownership and permission of /var/www/bihag.moops/public_html.

ls -l /var/www/bihag.moops/ 
total 4 
drwxrwxr-x 3 www-data www-data 4096 Aug 11 07:58 public_html

Folders inside public_html also belongs to the same group.

ls -l /var/www/bihag.moops/public_html/
total 8
-rwxrwxr-x 1 www-data www-data  191 Aug 11 07:54 index.html
drwxrwxr-x 2 www-data www-data 4096 Aug 11 07:59 logs

Still can't write to public_html. Even though I am the member of the same group. Why this discrimination?

touch home.php
touch: cannot touch 'home.php': Permission denied

Note: Even though this is a local machine. I don't want to use 777 permission.

Additionally:

lsattr /var/www/
--------------e----- /var/www/bihag.moops
--------------e----- /var/www/html

And

lsattr /var/
--------------e----- /var/mail
--------------e----- /var/log
--------------e----- /var/www

I am a maths teacher and have to teach my students over video in this lock down. Now all I want for them is to view expression and equations. I aim to achieve this by sharing my screen and using some sort of LaTex editor that is able to display the results on the go. I know there are some online tools. But is there any such application native to linux. I do not wish to build complex documents using this editor. Just some sort of split view where my latex will turn into expressions live as I type or after each statement.

I have on my hard disk three operating systems -

• Windows 10
• Windows 7
• Ubuntu 14.04.3

On the grub screen I have only one option for Windows. To boot to either of the windows version, I first have to select the windows (loader) from Grub Menu and then the specific window version from the Windows native boot menu.

Is it possible to have two separate entries for each windows version on the grub menu itself? All three operating system are on the same hard disk, of course, in different partitions.

I have written few simple console C# programs in Monodevelop but it seems they run in some emulated enviroment while debugging. The end result is a .exe file which does not runs natively on Ubuntu.

What I need to know is if Mono is same as Visual C# on Windows? Can we create native GUI applications with Monodevelop just as we can with QT Creator(Linux)/Visual Studio(Windows)? If yes, how? If no, why? Why we need Mono on Linux?

Are there some tools or commands I can use to send USSD codes for checking balance and data balance of the GSM SIM Card in my USB modem (Mobile broadband dongle)?

Installed Blender (2.62) from Software Center. The interface loads good but objects are not visible in any view. It shows that objects are selected but they appear no where. Even the default cube, lamp and camera are not visible.

Net-book Specs,

Intel Dual Core 1.6 GHz Processor
RAM 1GB
Resolution 1024*600
Graphics: Intel GMA 3600
OS: Ubuntu 12.04.1
Desktop Enviroment: LXDE and Unity

I have cedar-view graphics driver installed as suggested in additional drivers, it gives me native resolution and hardware accelerated X. I can play some games with nice frame-rates, like Irrlamb, Lugaru, XMoto and AssaultCube. Glxgears gives an average of 120 FPS.

Any reason why Blender is not working correctly?

I recently installed Cinnamon on my Ubuntu 12.04.1 and I loved the interface of its file manager Nemo, which I guess is also based on Nautilus. But I prefer Nemo over Nautilus and I want to remove Nautilus completely and have Nemo as my defaut File Manager.

The problem however is that removing Nautilus requires me to remove ubuntu-desktop too. Is it possible somehow to retain Ubuntu Desktop and remove Nautilus?

I am using Ubuntu 12.04.3 Kernel 3.8.33 on an Intel N2600/GMA3600 Netbook. Ubuntu currently runs in 1024*600 resolution which is perfect for my netbook.

However the graphic performance is very poor. I am stuck with Unity 2D and video playback is dreary. Glxgears reports framerates (<1) and CPU usage for glxgears is 100% (as reported by top). The driver in use is gma500_gfx.

I read somewhere that the proprietry drivers in repositories can give hardware accelarated video playback and OpenGL ES support. However, the cedarview-graphics-drivers fails to install with kernel>3.2 and Xorg>1.1.

I am planning on downgrading to Ubuntu 12.04.1,

where these drivers can be installed ?

Will it provide better video playback than gma500_gfx ?
