Ubuntu 15.04, Low resolution problem

[golden_eye_]

I hope that this driver (https://launchpad.net/~oibaf/+archiv...aphics-drivers) would work but its creating some problem (mentioned in previous post)

[sudodus]

Well, good luck and let us know your results

Can you post your latest /var/log/Xorg.0.log file as an atttachment ?

15.04 & 14.04 (with additional hardware enablement stack) should have had out-of-the-box support for this 2 year old CPU/GPU.

Here is the log.

Press CTRL+ALT+T and run xrandr. Reply with the results

In /etc/X11/xorg.conf, look for these two lines :

HorizSync 28.0 - 33.0
VertRefresh 43.0 - 72.0

and replace them with

HorizSync 30.0 - 83.0
VertRefresh 56.0 - 75.0

You can try setting your resolution to the desired level manually.
First, run this command, changing the example 1920x1080 resolution to the resolution you want:

cvt 1920 1080

That will spew out something like this:

# 1920x1080 59.96 Hz (CVT 2.07M9) hsync: 67.16 kHz; pclk: 173.00 MHz
Modeline "1920x1080_60.00"  173.00  1920 2048 2248 2576  1080 1083 1088 1120 -hsync +vsync

We're only interested in the chunk after the quotes and before the -hsync, e.g.

173.00  1920 2048 2248 2576  1080 1083 1088 1120

Use that in the next command to add a graphics mode:

xrandr --newmode clever_name 173.00  1920 2048 2248 2576  1080 1083 1088 1120

Now, add your new mode to your VGA output:

xrandr --addmode VGA1 clever_name

Finally, switch your VGA monitor to use it:

xrandr --output VGA1 --mode clever_name

Now that that works, you can make it take effect every time you log in. To do so, create the following files somewhere:
fix-resolution.sh with what is called a shebang line and then the last three commands you ran that got it working before, e.g.:

#!/bin/sh
xrandr --newmode clever_name 173.00  1920 2048 2248 2576  1080 1083 1088 1120
xrandr --addmode VGA1 clever_name
xrandr --output VGA1 --mode clever_name

fix-resolution.desktop with the following contents:

[Desktop Entry]
Name=fix resolution
Exec=/usr/bin/local/fix-resolution.sh

Now, copy the files to the appropriate places on your hard drive and make the script executable. From a terminal:

cp fix-resolution.sh /usr/local/bin
chmod +x /usr/local/bin/fix-resolution.sh
cp fix-resolution.desktop /etc/xdg/autostart

This will run the commands that force your monitor to the proper resolution every time someone logs into your computer.

Hope you get it to work!

1) I haven't found any /etc/X11/xorg.conf in 15.04 and created one using the command provided in this post[1]. There is no HorizSync and VertRefresh in this file. After creating this file, resolution has increased to 1024x768 from 640x480 and the graphics has become very slow.

2) If I try to execute the following command

xrandr --newmode clever_name 173.00 1920 2048 2248 2576 1080 1083 1088 1120

I get this error

Resolution 1280x1024 has been appeared in display option. When I select that option, it creates an error showing max and min resolution.
You can visualize the slowness of graphics. Screenshot taking window is also visible the screenshot!

i am really disappointed

[Ty_Scheun]

Are you using a VGA Port for your monitor? If its HDMI you are using, I could provide help for that
You can also manually set it with

xrandr -s 1280x1024

[Ty_Scheun]

Yet another way to change!

First open a terminalApplications >> Accesories >> Terminal


in the terminal type :
1)Code:

$ xrandr

(without the $ mark)
this will display the allowed resolutions
something like this :

Screen 0: minimum 320 x 200, current 1024 x 768, maximum 4096 x 4096
VGA1 connected 800x600+0+0 (normal left inverted right x axis y axis) 267mm x 200mm
800x600 85.1* +
640x480 75.0 60.0 
720x400 70.1

then type
2)Code:

$ cvt 1024 768

(any resolution that you want similar to this)

the output will be similar to this :

# 1024x768 59.92 Hz (CVT 0.79M3) hsync: 47.82 kHz; pclk: 63.50 MHz
Modeline "1024x768_60.00" 63.50 1024 1072 1176 1328 768 771 775 798 -hsync +vsync

3)Code:

 $ xrandr --newmode <Modeline>

(copy the modeline of the previous output to the place mode line)
for example :Code:

$ xrandr --newmode "1024x768_60.00"   63.50  1024 1072 1176 1328  768 771 775 798 -hsync +vsync

4)Code:

$ xrandr --addmode VGA1 1024x768_60.00

(here for VGA1 you have to use what ever that was there for $ xrandr output in step 1)

5)Code:

$xrandr --output VGA1 --mode 1024x768_60.00 

(replace VGA1 accordingly, remember to use the numbers within inverted commas in step 3 , after --newmode for 1024x768_60.00 )

***Running these would change your resolution but this is temporary.these steps were done to make sure that these commands work . After step 5 you should see the resolution change.If this is successful proceed to the next step


6)
Code:

$ sudo gedit /etc/gdm/Init/Default

(this will ask for your root password type the password and a text editor will appear)
in this you will see a text line like this
PATH=/usr/bin:$PATH
OLD_IFS=$IFS



just below this paste the step 3 to 5 commands
and then save it.

example :
#!/bin/sh
# Stolen from the debian kdm setup, aren't I sneaky
# Plus a lot of fun stuff added
# -George

PATH=/usr/bin:$PATH
OLD_IFS=$IFS
xrandr --newmode "1024x768" 70.00 1024 1072 1176 1328 768 771 775 798 -hsync +vsync

xrandr --addmode VGA1 1024x768_60.00

xrandr --output VGA1 --mode 1024x768

if [ -x '/usr/bin/xsplash' ];

then
/usr/bin/xsplash --gdm-session --daemon


this worked in karmic ......I think this will be helpful to you if you want know more about xrandr
