偶这边也遇到过你的问题,初步推测为10.04对显卡兼容问题(应该是内核),换成9.04就没问题了;
等待高人来解答此问题

ps:偶这边的是显示器上部分白竖线,下部分是黑屏,重启后又可正常一段时间(时间不固定,一般3个小时左右)

应该是找到解决方法了,今天上午我开机到现在还没有出现竖条纹+黑屏现象,估计是处理好了。
方法如下:
我的是intel 845板子,集成显卡。
1.sudo su
2.输入密码
3.sudo gedit /etc/modprobe.d/radeon-kms.conf
4.在文本中输入 i915 modeset=0,并保存,退出。(注意不要加逗号或者引号!)
5.重启后生效。
如果是ati的显卡,请参看下面资料:

Ubuntu从9.10升级到10.04后,发现开机后屏幕上出现全屏的闪烁短条纹。

经过一番折腾,发现是KMS的问题,Ubuntu10.04在内核2.6.32上默认开启KMS,于是就有了这个问题,开机选择2.6.31后就一切正常。

经过搜索,Ubuntuwiki有介绍。(附在文后)

关闭KMS后一切正常,而且我的显卡是:

ninehills@localhost:~$ lspci -nn | grep VGA

01:00.0 VGA compatible controller [0300]: ATI Technologies Inc RV515 [Radeon Mobility X1450] [1002:7186]

属于推荐不开启的范畴

X/KernelModeSetting
Kernel mode-setting (KMS) shifts responsibility for selecting and setting up the graphics mode from X.org to the kernel. When X.org is started, it then detects and uses the mode without any further mode changes. This promises to make booting faster, more graphical, and less flickery.


Configuring KMS on Lucid
By default, KMS is enabled by default for the -intel, -ati, and -nouveau drivers. It is not available for any other drivers at this time.

If you need to turn KMS *off* (I personally had to do it for Radeon Mobility X1400 and X1600), set modeset=0 for your kernel driver:


# ATI Radeon:echo options radeon modeset=0 > /etc/modprobe.d/radeon-kms.conf# Intel: (Note - see below)echo options i915 modeset=0 > /etc/modprobe.d/i915-kms.conf
The Nouveau video driver does not support non-KMS mode, instead you will need to install and use the xserver-xorg-video-nv driver.

The Intel video X driver as of version 2.9.1-1Ubuntu4 has been compiled as KMS-only; if you need to turn off KMS on -intel, you must use an earlier version than this. Such a version is available from the x-retro PPA.

X freezes (GPU lockups) are being experienced on i845, i855 and other 8xx chips.

We experimented with several different settings but could not find a combination which resolved all issues for all 8xx owners. Below are some of the settings that can be changed if the combination we picked for the release did not work for you.

NOTE: For Maverick workarounds have changed, please have a look at https://wiki.ubuntu.com/X/Bugs/Mavericki8xxStatus too.

GTT Incoherency Patch

NOTE: These patches are designed only for i855 chipsets. It is not supported for other i8xx chipsets.

Daniel Vetter has released a patch to hopefully solve the GTT incoherency problems.

Brian Rogers has packaged this fix as an experimental Natty (11.04) kernel.

Install the 855gm PPA and the patched kernel

https://launchpad.net/~brian-rogers/+ar ... es-testing

sudo add-apt-repository ppa:brian-rogers/graphics-fixes-testing
sudo apt-get update
sudo apt-get install linux-headers-2.6.37-graphics2+12 linux-headers-2.6.37-graphics2+12-generic linux-image-2.6.37-graphics2+12-generic

Stefan Glasenhardt has packaged his fix as two DKMS modules.

Install the updated -intel driver

https://launchpad.net/~glasen/+archive/intel-driver

sudo add-apt-repository ppa:glasen/intel-driver
sudo apt-get update && sudo apt-get upgrade

Install the 855gm PPA and the patched kernel modules

https://launchpad.net/~glasen/+archive/855gm-fix

sudo add-apt-repository ppa:glasen/855gm-fix
sudo apt-get update && sudo apt-get install dkms 855gm-fix-dkms

Reporting Results

Testing results should be reported upstream to the relevant bug report containing the patch at http://bugs.freedesktop.org/show_bug.cgi?id=27187.

Workarounds

Workaround A: Re-enable KMS

For release we made the decision to blacklist KMS for 8xx hardware. If you had found that beta1 and earlier Ubuntu had been working fine, this may be an effective workaround for you.

To turn KMS back on, run this command in a Terminal window and reboot:

echo options i915 modeset=1 | sudo tee /etc/modprobe.d/i915-kms.conf
sudo update-initramfs -u

In some cases, this bug causes i8xx users to boot into a blank screen on both the LiveCD/USB and a clean install or upgrade. To enable the above workaround in these situations, add "i915.modeset=1" to your kernel boot parameters.

From the LiveCD:

1) At the purple screen with a keyboard and stickfigure, press Enter to get to the menu.

2) Hit Enter to select your language, and then press F6 and then Esc.

3) Add "i915.modeset=1" after "quiet splash".

4) Press Enter to boot the LiveCD.

From an installation:

1) Hold down Shift while booting to enter the GRUB menu.

2) Press 'e' to edit.

3) Add "i915.modeset=1" after "quiet splash".

4) Ctrl+x to boot.

If adding "i915.modeset=1" to your boot parameters allows you to boot successfully, you then need to enter the command above into a terminal to make the changes permanent.

Workaround B: Switch to -vesa

Paste the following into /etc/X11/xorg.conf:

Section "Device"
Identifier "Configured Video Device"
Driver "vesa"
EndSection

Section "Monitor"
Identifier "Configured Monitor"
EndSection

Section "Screen"
Identifier "Default Screen"
Monitor "Configured Monitor"
Device "Configured Video Device"
EndSection

Switching to -vesa has been found to 100% stop the freezes. However, this regresses a lot of functionality: No 3D hw acceleration, no accelerated video, no HD resolutions, poor external monitor support. Probably other issues too.

Workaround C: Use a -intel DDX driver other than 2.9.1

Downgrading

A downgrade package to the 2.8.0 driver is available in the X-Retro PPA:

https://edge.launchpad.net/~ubuntu-x-sw ... ve/x-retro

A couple of users found this worked better than the 2.9 driver but they still saw freezes at a reduced frequency. So YMMV.

Also be aware there were performance issues with this version of the driver, so YMMV again. See ubuntugeek for some tips on tweaking X settings to work around the performance issues.

Upgrading

An upgrade package to the 2.11.0 driver is available in the X-Updates PPA:

https://launchpad.net/~ubuntu-x-swat/+archive/x-updates

Some users have reported that this helps their problems.

Workaround D: Use a kernel other than 2.6.32

Downgrading

Many users reported that downgrading to a 2.6.31 kernel resolved the issue completely. To boot a different kernel, hold down Shift while booting to enter GRUB, and then select a different kernel.

Upgrading

Upgrading to the mainline kernel has also solved the problem for most users. Be aware, however, that using a mainline kernel comes with some drawbacks:

1) You will lose all ubuntu-specific patches, such as ureadahead, which is responsible for the lightning-fast boot times.

2) You will not be able to use Proprietary Drivers from System->Administration->Hardware Drivers (i.e. nVidia, Broadcom).

3) While you will still be upgraded to new versions of Ubuntu kernels, the mainline kernel will not be upgraded to a new version. Thus, to ensure you have the most up-to-date mainline kernel for security and stability reasons, you will have to constantly check for a new mainline kernel release.

That said, to upgrade to the current mainline kernel:

32-bit users:

wget -c http://kernel.ubuntu.com/~kernel-ppa/ma ... 4_i386.deb http://kernel.ubuntu.com/~kernel-ppa/ma ... 34_all.deb http://kernel.ubuntu.com/~kernel-ppa/ma ... 4_i386.deb
sudo dpkg -i linux-headers-2.6.34-020634-generic_2.6.34-020634_i386.deb linux-headers-2.6.34-020634_2.6.34-020634_all.deb linux-image-2.6.34-020634-generic_2.6.34-020634_i386.deb

64-bit users:

wget -c http://kernel.ubuntu.com/~kernel-ppa/ma ... _amd64.deb http://kernel.ubuntu.com/~kernel-ppa/ma ... 34_all.deb http://kernel.ubuntu.com/~kernel-ppa/ma ... _amd64.deb
sudo dpkg -i linux-headers-2.6.34-020634-generic_2.6.34-020634_amd64.deb linux-headers-2.6.34-020634_2.6.34-020634_all.deb linux-image-2.6.34-020634-generic_2.6.34-020634_amd64.deb

Using Maverick Kernel

Backports of the Maverick kernel are available for Lucid using the Kernel Team PPA.

To install the backported kernel, run:

sudo add-apt-repository ppa:kernel-ppa/ppa
sudo apt-get update && sudo apt-get install linux-generic-lts-backport-maverick

This package will automatically update once a new Maverick kernel is released, and will also allow access to proprietary drivers and Ubuntu-specific patches included in the Maverick kernel. However, the backported kernel is not supported by the kernel team, so you should not submit bug reports or support requests against it.

Workaround E: Disable DRI

Paste the following into /etc/X11/xorg.conf:

Section "Device"
Identifier "Configured Video Device"
Driver "intel"
Option "DRI" "off"
EndSection

This disables 3D acceleration and will make graphics generally slower, but has been reported to help by some users.

Workaround F: Use UXA Rendering

Re-enable KMS, see above Workaround A (which just made boot-up more pleasing but did not help with X). Make sure the following section in /etc/default/grub doesn't contain KMS related settings. just:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
GRUB_CMDLINE_LINUX=""

if you had to change the grub file do "sudo update-grub"

Then follow the instructions "The Solution" "Method 2" here:

http://www.ubuntugeek.com/intel-graphic ... users.html

so that xorg.conf looks like:

Section "Screen"
Identifier "Configured Screen Device"
Device "Configured Video Device"
EndSection

Section "Device"
Identifier "Configured Video Device"
Option "AccelMethod" "UXA"
VideoRam 130560
EndSection

This way X now works flawlessly without any crashes at least for those with:

$ lspci -nn | grep VGA
00:02.0 VGA compatible controller [0300]: Intel Corporation 82852/855GM Integrated Graphics Device [8086:3582] (rev 02)

Workaround G: Re-enable KMS and disable DRI

Use Workaround A (re-enabling KMS) and Workaround E (disabling DRI). This gives no X.org crashes even with KDE, which in my computer at least crashed just after a few seconds of loading session (now lasted hours). Important: this workaround disables DRI, and therefore gaming performance is awful since there's not 3d acceleration. Tested on this hardware:

$ lspci -nn | grep VGA
00:02.0 VGA compatible controller [0300]: Intel Corporation 82845G/GL[Brookdale-G]/GE Chipset Integrated Graphics Device [8086:2562] (rev 01)

Some users has reported that this workaround makes their computer last much longer and then crash, so this workaround seems only to be able to reduce the problem but not fixes it.

Legacy Driver

Chris Wilson has released an intel graphics driver that re-introduces a GEM-less UMS codepath. Christopher James Halse Rogers has packaged these in his raof/aubergine PPA. It was hoped that this would result in a significantly more stable driver than was shipped with Ubuntu 10.04, but test results suggest that it is not significantly better. If you wish to try it, the results remain below.

NOTE: this should be moved to the maverick page as the "raof/aubergine" ppa has no lucid files.

Install the PPA packages

sudo add-apt-repository ppa:raof/aubergine
sudo apt-get update && sudo apt-get upgrade

Note: This will leave libdrm-nouveau1 as held-back. DO NOT force that upgrade; it will break things.

Disable KMS

Disable KMS by adding 'i915.modeset=0' to the GRUB_CMDLINE_LINUX_DEFAULT line in /etc/default/grub so it reads "quiet splash i915.modeset=0".

gksudo gedit /etc/default/grub
sudo update-grub

If you re-enabled KMS using Workaround A below, you must remove it using the following command before you'll be able to test this legacy driver.

sudo rm /etc/modprobe.d/i915-kms.conf
sudo update-initramfs -u

Uninstalling the Driver if it Doesn't Work

If the legacy driver does not work for you (e.g. you can no longer boot into an X session), follow these steps to manually restore your system from the shell:

1) Reboot into recovery mode and login as root,

2) Install ppa-purge and remove the

# apt-get install ppa-purge
# ppa-purge ppa:raof/aubergine

3) Remove the modesetting line you added to GRUB,

# nano /etc/default/grub
# update-grub

4) Reboot
