红帽全球峰会24.4. Display settings and device drivers
Some video cards have trouble booting into the Red Hat Enterprise Linux graphical installation program. If the installation program does not run using its default settings, it attempts to run in a lower resolution mode. If that fails, the installation program attempts to run in text mode.
There are several possible solutions to resolve display issues, most of which involve specifying custom boot options:
For more information, see Console boot options.
| Solution | Description |
|---|---|
| Use the basic graphics mode | You can attempt to perform the installation using the basic graphics driver. To do this, either select Troubleshooting > Install Red Hat Enterprise Linux in basic graphics mode from the boot menu. |
| Use the text mode | You can attempt to perform the installation using the text mode. For details, refer to Installing RHEL in text mode. |
| Specify the display resolution manually | If the installation program fails to detect your screen resolution, you can override the automatic detection and specify it manually. To do this, append the inst.resolution=x option at the boot menu, where x is your display’s resolution, for example, 1024x768. For more information, see Customizing boot options. |
| Use an alternate video driver | You can attempt to specify a custom video driver, overriding the installation program’s automatic detection. |
| Perform the installation using RDP | If the above options fail, you can use a separate system to access the graphical installation over the network, using the Remote Desktop Protocol (RDP). |
- If specifying a custom video driver solves your problem, you should report it as a bug in Jira. The installation program should be able to detect your hardware automatically and use the appropriate driver without intervention.
