Ubuntu Installation :: Upgrade To 10.04 Leads To Loss Of Correct Screen Resolution / Wireless Networking / Sound
May 4, 2010
Excited at seeing the new features in 10.04, I clicked the Upgrade button tonight. I am now really regretting it! Problems:
1. My screen resolution should be 1280x1024 but the System>Preferences>Monitors control panel only shows 1024x768.
I think I have onboard Realtek graphics. Do I need to install proprietary drivers? Everything worked fine out of the box with 9.10!
2. The sound isn't working. Again I think I have onboard Realtek sound, and again it used to work fine without any intervention from me...
3. Although on first startup wireless networking was working fine, I restarted to see if that would solve the display issue, and wireless networking stopped working too!
I have an RaLink wireless card.
When I used Grub to choose 2.6.31.20, I got some error messages at startup (e.g. mount couldn't mount /dev), but then it did eventually start up and the sound and wireless networking are working again. But the resolution is still not fixed. It is now offering 1152x864, which it didn't previously, but no 1280x1024 (my screen's native resolution).

I installed Squeeze with LXDE on my old 600MHz Celeron, 256MB ram computer. But, every time I boot, the screen resolution is wrong. I can set it right with a few clicks of the mouse, but next time I boot up it has reverted to the wrong setting. I found that this problem has been reported on the LXDE forum, but the official response seems to be that it is not their problem.
How do I get the correct setting to stick?

I just got a DVI cable so I can have a dual monitor setup, (one VGA, one DVI monitor), and when the DVI cable is plugged into our 20" widescreen, the correct resolution (1680 x 1050), a "No Signal" error message will appear on the monitor. When the resolution is lower with the DVI cable, it will show up, but everything will be a bit bold and blurry. When I plug our VGA cable into the VGA slot in this monitor, everything shows up fine.

I have some experience with Linux (mostly Ubuntu) but absolutely none with Fedora. In fact I have needed to re-install twice just to get to this stage. I now have a fully updated Fedora 14 Gnome desktop. I have (finally) got Nvidia graphics drivers up and running. I can open the Nvidia Settings screen and everything looks ok except that the desktop screen resolution doesn't seem correct. I have a Sony Vaio with default screen resolution of 1920x1200. In Nvidia settings it was set to AUTO, but I've changed that as root user to 1920x1200 with a refresh rate of 60 Hz and rebooted. My desktop looks quite good, but it's not 1920x1200 - maybe 1600x1200? Perhaps. How do I confirm the current resolution?
I have run
Code:
glx info | grep direct
and the output is
Code: direct rendering: Yes
GL_EXT_Cg_shader, GL_EXT_depth_bounds_test, GL_EXT_direct_state_access,
Which I presume is ok?

I have upgraded my machine from Ubuntu 10.10 to 11.04, initially it worked fine, and then I had to replace my VGA cable - now I wind up with a screen resolution that is too low.
It is possible to change the resolution with xrandr, but is there a way to set this permanently (currently it resets on startup)? Previous versions have altered the xorg.conf file and just added a new resolution setting - but I think these settings have been moved out of xorg.conf. Does anyone have any ideas how to change the screen resolution settings permanaently in 11.04?

I have a 1920x1200 monitor that was displaying correctly under 10.4, and after the upgrade to 10.10 it is displaying at 1280 x 720 (the highest resolution it has), and does not list 1920x1200How can I ask 10.10 to display at 1920x1200?

I'm using two screens where one Is cheep Denver TV screen with DVD player. I have just install Jessie on my PC. Before i had Windows and there was no problems finding correct resolution for this screen. Now Jessie recognize it as Unknown and the maximum resolution I can set is 1024x768 what is way to small even for this screen. At Windows resolution was something over 1200px wide. The worst thing about it is that this resolution stretches the display really ugly. You may think I'm making big deal of nothing but for me it is actually a deal. I'm graphical designer and I need to see display as it is.

I got a notification that there was an upgrade available today in ubuntu 9.10 64, after the update i restarted my system and while booting i encountered this error message:
Kernel panic - not syncing : VFS : Unable to mount root fs on unknown - block (8,17)
does this have something to do with the OS looking at the wrong hd?
theres no command prompt to actually do anything and i tried booting in safe mode and had the same problem. Let me know what i can do!

I just set up my dad's pc with Debian Sqeeze. It runs perfectly fine and after trying a lot of distro's Debian is the only one that will not crash or freeze up X. Now we're forced to using my own 17" monitor instead of his 19" wide screen since the max res is 1280 x 1024 in Sqeeze. What he needs is 1360 x 768. I found out in the wiki that xorg.conf needs to be edited. Since the file does not exist it needs to be created by running "Xorg -configure" in tty after stopping GDM. when running the "Xorg -configure" command this is the output;
" vmware: Please ignore above "FATAL: Module vmwgfx bot found."
(++) Using config file: "/root/xorg.conf.new"
(==) Using system config directory "/usr/share/X11/xorg.conf.d"
Number of created screens does not match number of detected devices.
Configuration failed. "
It's an Intel Sandy Bridge integrated graphics chip. I've tried running "Xorg:1 -configure" as mentioned in a forum but that simply gives me a "unknown command" answer.

When my notebook boots I get a high screen resolution. However, when I login it seems to go to a lower resolution that is not clear. I think this all started when I updated to a new kernel. So I reinstalled the nvida drivers using leigh's guide. However, I still can't seem to get it to display correctly.
Code:

I've upgraded from Karmic 64-bit kubuntu to the RC build for Lucid. I have two pcs connected to two monitors via an Aten dual head KVM switch. With the new release I only get a background slideshow on one monitor. I can get an image on the first monitor by right clicking and choosing Next Wallpaper image, but it never changes. When I select Desktop Activity Settings both monitors go entirely blank, except for the mouse cursor. The Display Multiple Monitors screen has ticks in all the multiple monitor checkboxes and Identify All Displays correctly identifies both monitors.

I cant seem to install Ubuntu 9.10 at all. At 15% I get the following Error Message Input/output Error During Read On/dev/sda then I get the creation of swapspace in partition #5 of SCSI1(0,0,0) (SDA) Failed. Ive tried 6 times already. Im getting no sound at all. How can I change the screen resolution. 800 x 600 is the highest it will go. Im getting really discouraged with Ubuntu. Alot of people seem to have the same problems I am having but there is no solutions. I've checked the MEMTEST and passed, done a disk check and passed.

I have tried the tips, and to the best of my ability understand the later posts from the sticky post "Graphics Resolution" however I seem to keep reverting back to the blank screen. I did this:
Quote: ATI TIPS: Note that some ATI cards need flgrlx and some do not... If not then this workaround sometimes works: (Found this in another thread / credit to Quote: Originally Posted by surgus View Post

1. When the boot hangs, press ctrl+alt+f1.
2. Login as user with root privileges.
3. Type "cd /usr/share/ati" and press enter.
4. Type "sudo sh ./fglrx-uninstall.sh" and press enter.
5. Type "sudo reboot".
The above only works for some but not all, depending on what card you have and whether it actually is supported by additional drivers (proprietary). All at the moment, mostl seem to need "nomodeset radeon mode=X", where x= 0 or 1... Some ATI cards are not working with the current natty kernel, but are working with the older 2.6.37 kernel or the proposed 2.6,38.9 kerne (please see post 2)l Sometimes (rarely) it'll work but more often it won't, and in the two times it's worked I haven't known how to get it to remember the setting permanently- keep in mind I have no idea what that last paragraph about x= 0 or 1 means.

Loss of internet connection after upgrade from 8.04 to 8.10 Like the title says, I lost my internet connection after upgrading my Ubuntu system from 8.04 to 8.10.I used the downloaded automated method. It appeared to work fine on its initial reboot into 8.10. But I noticed the internet icon indicated loss of connection. Even so, I was still able to browse the net through Firefox. But then when I rebooted the next day the opposite was true: the connection icon indicated connection, but Firefox would not actually connect, nor would update manager. It has been like this since. This is a dual boot machine, and the Windows XP Pro side still connects to the internet as usual, no problems.So how can I make my new 8.10 system connect to the internet?
I use a Motorola SB4200 cable modem

I have a new Toshiba Satellite L450, and decided to run Ubuntu, which is new to me. I am running a 64 bit Karmic, and there is no driver that works. So, to make a long story short: a friend helped me get a driver on my Desktop, namely: rtl8192se_linux_2.6.0100.1012.2009_64bit.tar.gz We had it working, but when I let in the first large batch up updates, it kicked the driver out. I found instructions, installed it again. I let in the next updates, and it kicked out again, and this time the instructions don't work. So, I have two sets of questions:
1. Will updates always undo my wireless? Are there certain updates I should avoid if I want the wireless to stay up and running? (I just assumed the thing to do is just get the updates -- though I am guilty of having no idea what they were about.)
2. Did the updates cause one of my instrucitons to no longer work, or need to be modified?
They were as follows:
sudo apt-get install build-essential
cd ~/Desktop
sudo tar -xvzf rtl8192se_linux_2.6.0100.1012.2009_64bit.tar.gz
That 'sudo tar -xvzf...' operation is the one that stops me. Is there something to change in that line? It goes on:
cd rtl8192se_linux_2.6.0100.1012.2009_64bit
[Code]...
this worked the first time I tried it. I posted this earlier under 'hardware', and do not know how to get that post off, so I typed it here once I realized.

I have a hp dv3 laptop which dual boots Win7 and Ubuntu 9.1 64 bit. I have no issues with my wireless adapter in Win7, but I lose connection after a couple of hours in Ubuntu. When connection is lost it is not possible to view any wireless signals, the adapter is basically turned off. The only way to restore the connection is to reboot, then Ubuntu will again automatically connect to my WP2 encrypted router. My wireless adapter is a AR928X made by Atheros.

For most of today I had my internet connection dropping out on me intermittently. I assumed it was a provider issue, as it has been unreliable in the past. After it dropped out for good, and I could not print through network, I realised it was not a provider issue. All the other computers in the house were connected, including another ubuntu box. Only the MacBook Pro 5,5 was not able to connect. The network manager indicated I was connected to the network, throughout the whole time.
A number of restarts with the kernel I normally use (2.6.31-19) including one in recovery mode, yielded no change, but a restart with the 2.6.31-20 kernel resulted in connectivity. Finally, perhaps by chance, wireless started to work again on the 2.6.31-19 kernel, after I once booted into the Mac OS, and then back into Karmic. How I might go about diagnosing, obviously in hindsight, what happened? I suppose I should look in the log files, but I have no idea where exactly, and what to look for.

I have ubuntu lucid running on Dell 230 PC, linksys WPN600 N wireless PCI network card connecting to a Cisco E3000 dual channel router.
Kernel: 2.6.32-33-generic
Installed Ralink driver v2.4.0.0
iwconfig shows that the bit rate is 130Mb/s and link quality is 98/100. I'm using the wcid network manager instead of defaul gnome one. I'm getting lots of packet loss and performance is very bad. The connection is practically unusable. I've tried installing the compat wireless backport package but that did not work at all.

The problem is I have a wireless Belkin router which I can connect to, but after being connected for a few minutes the net disappears (cuts from the router) and my laptop will have to reconnect again to the router for internet to work again. After a few minutes (or seconds in some cases) the connectivity loss will happen again over an over.
How to fix this problem or some things I can try, I've tried updating to two different firmwares, two different channels and resetting the router. The biggest problem I find is that this happens on both my laptop, another laptop in the house and also my tablet PC but doesn't happen on two other laptops in the house, I've also tested with windows 7 and Ubuntu with my laptop.
My laptop wireless card is Atheros AR9285 802.11b/g/n WiFi Adapter

I am running Slackware 13.0 on a old dell dimension 4500. The install went fine. sound worked, graphics where good. Everything was going perfect. until i worked on wireless.i have a realtek rtl8185 wireless chipset card. I got the wireless. Linux wireless driver. It worked on both Mint 5.0 and backtrack 4.0.so I untar the file. cd to the dir and type make then make install and reboot. like I have always done.
I was having to fight with wpa_gui and finally got it working but then it would go in and out on the connect and disconnect feature. so I tried using iwconfig. did not get muc luck with that either so i installed wicd and finally got a ip address after fighting with it would give me in a ping like 75% packet loss. so I read a lot of post and try to find stuff before I post. and while reading I learned that you guys normally ask for info on the hardware and software so here you go. but I will say first that I read about adjusting the mtu to fix packet loss, I showed some of the changes I made in it around the pings I know it is a mess I am sorry I tried to make it readable. if you need more information let me know. I cant get online using a web browser or if I can only for one or two pages. any help would be great. thank you.

A few days ago I made the mistake of upgrading to Ubuntu 10.04 LTS, and subsequently had nothing but trouble. My volume icon disappeared and for the life of me I couldn't find it or reinstall it. An eerily Windows-like chat icon has appeared next to my login name that I didn't ask for, and more importantly my handbrake program (Matroska encoder) completely stopped working.
I've learned in the past that LTS editions are not normal upgrades, and I should best avoid them. But this one appears from the Ubuntu homepage to be the standard upgrade from Karmic to Lucid. I've had to completely reinstall Karmic on my workstation just to be able to carry on as normal, but the laptop seems to be coping ok with the LTS edition. Can anybody tell me if this LTS is now the default upgrade for Lucid, or is this just a regular LTS and I should wait for my standard one to come out?

I am recently trying to get a steady wireless connection running. I am currently using the default settings/driver Fedora 13 is stocked with. As my internet browsing is somewhat up and down in load times, I decided to check in a video game which is generally a good test for me. haha I am harshly spiking and cannot find the source of my problem so my guess is a driver issue.

Code:
It is is seemingly right, my Windows 7 harddrive works just fine, this is just one last of the few issues I'm having from fully formatting my winblows HD to use as Linux storage.
I cannot find any native AR5008 Linux Drivers for my card and it has been a frustrating day. I guess I'm not cut to be a network analyst just yet.

I am using a 15" CRT Samsung monitor and when I upgraded 10.10, the screen resolution became 800x600 and I am not able to increase the resolution of it. This was working fine with 10.04 version.
Below is the o/p for "xrandr":
xrandr: Failed to get size of gamma for output default
Screen 0: minimum 800 x 600, current 800 x 600, maximum 800 x 600

Out of the blue a dialog popped up requesting that I enter the key for my home wireless network. This is of course unexpected since the correct key is defined for that network in my network config. I entered the correct key but it was rejected. I then clicked on the network manager icon in the task bar. Contrary to normal behavior this did not show either my home network or any of the other wireless networks from my neighbors. The only resolution I could find to restore the wireless network was restarting my system. This seems excessive.

i have installed ndiswrapper, and the correct drivers for the wireless card.
Code:
ndiswrapper -l:
bcmwl5a : driver installed
device (14E4:4320) present
I seemed to be having a conflict with the generic drivers which loaded for my wifi device 'b43-pci-bridge' and the ndiswrapper drivers i installed.
So i ran the command 'rmmod ssb' and now my broadcomm wireless device is "unclaimed"

I have 2 laptops running Ubuntu 10.04. One connects to my Linksys wireless modem fine while the other does not. The one that does not connect, will connect fine within the instances of Windows XP SP3 and Puppy Linux 5.1 that run on the same laptop. Ubuntu wireless worked fine with version 8.04 on this laptop before upgrading to 10.04.
When trying to connect within 10.04, Ubuntu pops up the dialog box to enter the authentication key. It rejects the correct key, and after a moment, pops up the same dialog box asking for the key again. I'm using WEP 40/128-bit encryption and the key I enter in the dialog box is the correct 26-character key.
The laptop is a Toshiba Satellite Pro 6000 (1g ram/40g disk). Here are some vital outputs root@user-laptop:/home/bsmis# iwconfig

I have just installed Ubuntu 9.10 netbook remix for my new laptop. I've tried at great length to install the correct drivers to get my wireless up and running. I'm currently trying to install the Broadcom driver for my 802.11g wireless card. I have downloaded the headers and tools for ubuntu and am proceeding with the instructions given on [URL].
But when I get to these steps I come unstuck
# mkdir hybrid_wl
# cd hybrid_wl
# tar xzf <path>/hybrid-portsrc.tar
I can make the directory and open it but when it comes to the third step I get a message saying that there is no such file or directory.
