我正在使用具有 GeForce GTX 1050 Ti 移动显卡的 MSI GL62M 7REX 笔记本电脑。当我使用 Ubuntu 19.10 时,我能够通过以下方式处理屏幕撕裂:
- 与此答案类似,我打开终端并输入
sudo gedit /etc/default/grub
打开 gedit 的内容如下:
# If you change this file, run 'update-grub' afterwards to update
# /boot/grub/grub.cfg.
# For full documentation of the options in this file, see:
# info -f grub -n 'Simple configuration'
GRUB_DEFAULT=0
GRUB_TIMEOUT_STYLE=hidden
GRUB_TIMEOUT=10
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
GRUB_CMDLINE_LINUX=""
# Uncomment to enable BadRAM filtering, modify to suit your needs
# This works with Linux (no patch required) and with any kernel that obtains
# the memory map information from GRUB (GNU Mach, kernel of FreeBSD ...)
#GRUB_BADRAM="0x01234567,0xfefefefe,0x89abcdef,0xefefefef"
# Uncomment to disable graphical terminal (grub-pc only)
#GRUB_TERMINAL=console
# The resolution used on graphical terminal
# note that you can use only modes which your graphic card supports via VBE
# you can see them in real GRUB with the command `vbeinfo'
#GRUB_GFXMODE=640x480
# Uncomment if you don't want GRUB to pass "root=UUID=xxx" parameter to Linux
#GRUB_DISABLE_LINUX_UUID=true
# Uncomment to disable generation of recovery mode menu entries
#GRUB_DISABLE_RECOVERY="true"
# Uncomment to get a beep at grub start
#GRUB_INIT_TUNE="480 440 1"
我编辑
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
并GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nvidia-drm.modeset=1"
保存了文件。打字
nvidia-smi
返回了以下细节:

现在我知道我的 Nvidia 驱动程序的主要版本是我
435
下一步需要的。根据这个指令(post #5),我创建了一个
.conf
文件,/etc/modprobe.d/
其中包含以下行:options nvidia_435_drm modeset=1
.之后,我运行
sudo update-initramfs -u
并重新启动了我的机器。sudo cat /sys/module/nvidia_drm/parameters/modeset
然后返回Y
并解决了问题。
在我升级到 Ubuntu 20.04 之后,这些选项还是一样的。内核参数依然完好,里面的.conf
文件/etc/modprobe.d/
依然存在。此外,Nvidia驱动程序的编号仍然正确,但屏幕撕裂再次发生。
尝试编辑 Nvidia X 服务器设置无济于事,因为如下所示:
这就是我尝试此处描述的对我有用的其他解决方案的原因。
如何使用 Ubuntu 20.04 解决此问题?
